Kugadzirwa kwejira regirazi rakachekwa neshinda kunosanganisira kutora jira regirazi (shinda isina kukoshwa inogona kushandiswawo) uye kuicheka kuita tambo refu dze50mm uchishandisa banga rekucheka. Tambo idzi dzinobva dzapararira uye dzakarongedzwa zvisina kurongeka, dzichigara pabhandi resimbi isina ngura kuti dzigadzire jira. Matanho anotevera anosanganisira kuisa chinhu chinosunga, chinogona kunge chiri muchimiro chenamira yekupfapfaidza kana chinamira chinopfapfaidzwa mumvura, kuti chisunge tambo dzakachekwa pamwe chete. Ramba racho rinozoomeswa zvakanyanya uye rinogadziriswazve kuti rigadzire jira rakachekwa neshinda kana jira rakachekwa neupfu.

I. Zvishandiso Zvisina Kugadzirwa
Girazi rinowanzoshandiswa muzvigadzirwa zvefiberglass imhando yecalcium-aluminium borosilicate ine alkali iri pasi pe1 muzana. Rinowanzonzi "E-glass" nekuti rakagadzirwa kuti rishandiswe mukudzivirira magetsi.
Kugadzirwa kwegirazi fiber kunosanganisira kutakura girazi rakanyungudutswa kubva muchoto chinonyunguduka kuburikidza neplatinum bushing ine maburi madiki akawanda, richitambanudzwa kuita girazi filaments. Pakutengeserana, filaments idzi dzinowanzova nedhayamita iri pakati pe9 ne15 micrometers. Filaments idzi dzinoputirwa nehukuru husati dzaunganidzwa kuita filaments. Filaments dzegirazi dzakasimba zvikuru, dzine simba guru rekusunga. Dzinoratidzawo makemikari akanaka, dzinodzivirira hunyoro, dzine hunhu hwakanaka hwemagetsi, hadzina kurwiswa nehutachiona, uye hadzitsve ne1500°C—zvichiita kuti dzive dzakakodzera kushandiswa muzvinhu zvakasanganiswa.
Machira egirazi anogona kushandiswa mumhando dzakasiyana-siyana: akachekwa kuita marefu mapfupi (“tambo dzakachekwa”), akaunganidzwa muzvisungo zvakasungwa zvisina kusimba (“zvisungo”), kana kurukwa kuita machira akasiyana-siyana kuburikidza neshinda dzinotenderera uye dzinotenderera. MuUK, rudzi rwezvinhu zvegirazi fiber zvinoshandiswa zvakanyanya ijira resimbi rakachekwa, iro rinogadzirwa nekucheka jira regirazi fiber kuita marefu angangoita 50mm uye kuabatanidza pamwe chete uchishandisa polyvinyl acetate kana polyester binders, zvichiita kuti zvive machira. Huremu hwejira resimbi rakachekwa hunogona kusiyana kubva pa100gsm kusvika 1200gsm uye hunobatsira pakusimbisa kwakazara.
II. Danho rekushandisa Binder
Magirazi anotakurwa kubva kuchikamu chinogadzika kuenda kubhandi rekufambisa, uko kunoiswa binder. Chikamu chinogadzika chinofanira kuchengetwa chakachena uye chakaoma. Kuisa binder kunoitwa uchishandisa maapplicator maviri ekubikisa hupfu uye mapombi emvura akatevedzana asina mineralized.
Pamachira akachekwa, kumativi ese ari maviri ekumusoro neapasi, mvura yakapfapfaidzwa zvishoma nezvishoma inoiswa. Danho iri rakakosha kuti chibatiso chinyatsonamira. Zvishandiso zveupfu zvakakosha zvinoita kuti upfu hupararire zvakaenzana. Zvishandiso zvepakati pezvishandiso zviviri zvinobatsira kutamisa upfu pasi pemachira.
III. Kusunga neEmulsion
Sisitimu yemaketeni inoshandiswa inoita kuti chibatiso chipararire zvakanaka. Chibatiso chakawandisa chinotorwa kuburikidza nesisitimu yekusveta yakakosha.
Sisitimu iyi inobvumira mweya kutakura chinhu chinosunga chinowedzera kubva pamubhedha uye chinhu chinosunga chinonyatsogoverwa zvakaenzana, zvichibvisa chinhu chinosunga chinowedzera. Zviri pachena kuti tsvina yakaseferwa iri muchinhu chinosunga inogona kushandiswazve.
Chinosungirirwa chinochengetwa mumidziyo muimba yekusanganisa uye chinotakurwa kubva muzvirongo zvidiki zviri pedyo nefekitori yemachira kuburikidza nemapombi ane simba shoma.
Midziyo yakakosha inochengetedza mwero wetangi risingachinji. Chinodzokororwa chinoiswawo mutangi. Mapombi anotakura chinonamira kubva mutangi kuenda padanho rekushandisa chinonamira.
IV. Kugadzirwa
Mati yesimbi yakachekwa negirazi isimbi isina kurukwa yakagadzirwa nekucheka tambo refu kuita 25-50mm, wodziisa panzvimbo yakatsetseka, wodzibatanidza pamwe chete nebinder yakakodzera. Kune mhando mbiri dzebinders: upfu ne emulsion. Hunhu hwezvinhu zvakasanganiswa hunoenderana nekusanganiswa kwedhayamita yefilament, kusarudzwa kwebinder, uye huwandu, zvinonyanya kutsanangurwa nerudzi rwemati inoshandiswa uye maitiro ekuumba.
Chinhu chinoshandiswa kugadzira machira esimbi akachekwa ikeke regirazi rinogadzirwa nevanogadzira fiber, asi mamwe anoshandisawo machira esimbi, pamwe chete kuchengetedza nzvimbo.
Kuti mat ive yemhando yepamusoro, zvakakosha kuva nehunhu hwakanaka hwekucheka fiber, simba shoma remagetsi risingachinji, uye kushandiswa kwakaderera kwe binder.
V. Kugadzirwa kweFekitori kunosanganisira zvikamu zvinotevera:
Fiber Creel
Maitiro Ekucheka
Chikamu Chekuumba
Sisitimu Yekushandisa Binder
Ovheni yekuomesa
Chikamu Chekudzvanya Chatonhora
Kuchekerera uye Kumonera
VI. Nzvimbo yeCreel
Zvigadziko zvecreel zvinotenderera zvinoiswa pafuremu zvine huwandu hwakakodzera hwemabobbins. Sezvo zvigadziko izvi zvecreel zvichitakura makeke efiber, nzvimbo yecreel inofanira kunge iri muimba ine hunyoro hunodzora hunyoro ine hunyoro hwe82-90%.
VII. Midziyo yekucheka
Shinda inobviswa kubva mumakeke ari kufamba-famba, uye banga rega rega rinocheka rine tambo dzakawanda dzinopfuura nepakati paro.
VIII. Chikamu Chekuumba
Kugadzirwa kwetambo dzakachekwa kunosanganisira kugoverwa kwakaenzana kwetambo dzakachekwa panguva dzakaenzana mukamuri rekugadzira. Midziyo yega yega ine mota dzinomhanya zvakasiyana-siyana. Midziyo yekucheka inodzorwa yega kuti ive nechokwadi chekuti tambo dzakachekwa dzakaenzana.
Mhepo iri pasi pebhandi rekufambisa zvinhu inodhonzawo machira kubva pamusoro pebhandi. Mhepo inoburitswa inopfuura nemuchina wekuchenesa.
IX. Ukobvu hweGlass Fiber Yakachekwa Strand Mat Layer
Muzvinhu zvakawanda zvakagadzirwa nefiberglass, mati egirazi akachekwa nefiber anoshandiswa, uye huwandu nenzira yekushandisa mati etambo akachekwa zvinosiyana zvichienderana nechigadzirwa uye maitiro acho. Ukobvu hwemati hunoenderana nemaitiro anodiwa ekugadzira!
Semuenzaniso, mukugadzirwa kwemidziyo yekutonhodza fiberglass, jira rimwe chete rinoputirwa neresin, richiteverwa nejira rimwe chete remachira matete kana jira re2. Pakati, jira 6-8 remachira e04 rinoiswa, uye rimwe jira remachira matete rinoiswa pamusoro kuti rifukidze majoini emukati mejira. Muchiitiko ichi, jira mbiri chete dzemachira matete dzinoshandiswa pamwe chete. Saizvozvowo, mukugadzira denga remotokari, zvinhu zvakasiyana-siyana zvakaita sejira rakarukwa, jira risiri rakarukwa, purasitiki yePP, machira matete, uye furo zvinosanganiswa muzvikamu, nejira matete rinowanzo shandiswa muzvikamu zviviri chete panguva yekugadzira. Kunyangwe pakugadzira denga remotokari yeHonda, maitiro acho akafanana. Saka, huwandu hwemachira akachekwa anoshandiswa mufiberglass hunosiyana zvichienderana nemaitiro acho, uye mamwe maitiro angasade kushandiswa nepo mamwe achida.
Kana tani imwe chete yefiberglass ikagadzirwa uchishandisa mati neresin zvakachekwa, huremu hwemati neresin zvakachekwa hunoita 30% yehuremu hwese, inova 300Kg. Nemamwe mashoko, huwandu hweresin hunosvika 70%.
Huwandu hwemachira etambo akachekwa anoshandiswa pakuita zvakafanana hunoenderanawo nekugadzirwa kwechikamu. Kugadzirwa kwechikamu kunoenderana nezvinodiwa nekanika, chimiro chechigadzirwa, zvinodiwa pakupedzwa kwenzvimbo, nezvimwe zvinhu.
X. Maitiro Ekushandisa
Kushandiswa kwejira regirazi risina alkali-free fiber rakachekwa riri kuramba richipararira uye rinosanganisira nzvimbo dzakasiyana-siyana dzepamusoro-soro dzakadai semotokari, zvemugungwa, zvendege, zvekugadzira simba remhepo, uye zvekugadzira zvemauto. Zvisinei, ungasaziva nezvezvinodiwa zvejira regirazi risina alkali-free fiber rakachekwa. Pazasi, tichataura nezvezvinodiwa zvepasi rose maererano nehuwandu hwealkali metal oxide, kutsauka kwenzvimbo yeyuniti, huwandu hunobvira, huwandu hwehunyoro, uye simba rekupwanya tensile:
Zviri Musimbi yeAlkali
Huremu hwe alkali metal oxide mugirazi risina alkali fiber rakachekwa netambo hahufanirwe kudarika 0.8%.
Nzvimbo Yechikamu Huru
Zviri Mukati Zvinobvira Moto
Kunze kwekunge zvataurwa neimwe nzira, huwandu hwemoto hunofanira kunge huri pakati pe1.8% ne8.5%, nekusiyana kukuru kwe2.0%.
Hunyoro
Hunyoro hwemachira ekushandisa chinonamira cheupfu hahufanirwe kudarika 2.0%, uye pamachira anoshandisa chinonamira che emulsion, hahufanirwe kudarika 5.0%.
Simba Rekupwanya Simba
Kazhinji, mhando yejira regirazi risina alkali rinochekwa nefiber rinozadzisa zvinodiwa pamusoro apa kuti zvionekwe sezvinoenderana nezvinodiwa. Zvisinei, zvichienderana nekushandiswa kwechigadzirwa, maitiro ekugadzira anogona kunge aine zvinodiwa zvepamusoro zvekusimba kwekusimba uye kutsauka kwehukuru hwenzvimbo. Saka, zvakakosha kuti vashandi vedu vekutenga vazive maitiro ekugadzira zvigadzirwa zvavo uye zvinodiwa chaizvo zvejira regirazi rakachekwa kuitira kuti vatengesi vagone kugadzira zvinoenderana nazvo.
