Mukati meumbozha, mahoods anopenya, mheremhere inokatyamadza… zvese zvinoratidza kuzvikudza kwemota dzemhando yepamusoro, dzinoita kunge dziri kure nehupenyu hwevanhuwo zvavo, asi unoziva here?Muchokwadi, mukati uye mahoods emota idzi akagadzirwa ne fiberglass zvigadzirwa.

Pamusoro pemotokari dzemhando yepamusoro, vanhuwo zvavo vakawanda vanotyaira mota nemarori anotakura zvinhu, zvese zvinogadzirwa negirazi fiber.Zvinogona kutaurwa kuti kushandiswa kwekushanda kwegirazi fiber kunogona kuwedzerwa nekusingaperi.

Parizvino, girazi fiber-yakasimbiswa mota chikamu chinoumba zvinhu zvinogona kukamurwa kuita marudzi maviri: thermoplastic uye thermosetting.Maitiro ekugadzira ezviviri akasiyana, uye mashandisirwo akasiyana zvakare.Thermosetting glass fiber products for LFT inonyanya kushandiswa kumotokari dzemukati zvikamu, zvakadai semabhuraketi epaneti yezviridzwa, mabhokisi ematayi, mabheji epamberi uye zvimwe zvisiri zve auto frame zvikamu;thermoset SMC fiberglass zvigadzirwa zvinonyanya kushandiswa kune mota hoods, mabumpers, uye emafuta tangi separators.Thermal zvivharo uye zvimwe zvemotokari zvimiro zvikamu.
Nekuvandudzwa kweindasitiri yemotokari uye nekusimudzirwa kwekuchengetedza simba uye pfungwa dzekuchengetedza kwezvakatipoteredza, mota dzisina kuremerwa dzave tsika yakajairika.Kushandiswa kwemafuta emotokari kunonyanya kuenderana nekufambiswa kweinjini uye huwandu hwese hwemotokari.Pamusoro pekuchengetedza hutano hwese, kushanda uye mutengo wemotokari, kuderedza uremu hwemotokari kunogona kuwedzera zvinobudirira simba rekubuda uye kubata, kuderedza kushandiswa kwemafuta, uye kuderedza kubudiswa kwemhepo.Zvidzidzo zvakaratidza kuti kune yega yega 10% kuderedzwa kwehuremu hwemotokari, kushandiswa kwemafuta kunogona kudzikiswa ne6-8%.Kutsiva simbi yechinyakare negirazi fiber inogona kuderedza uremu hwemotokari zvakanyanya.

Zvigadzirwa zveSMC chikamu chakakosha chezvikamu zvemotokari.Maitiro ekudzikisa huremu hwemotokari nekuvandudza mashandiro ayo inyaya yekukurumidzira kuti vagadziri vemotokari vagadzirise.
Parizvino, iyo inonyanya kuzivikanwa nzira muindasitiri ndeyekutsiva echinyakare mafirita neasina girazi mabheji, nekudaro kuderedza density yepepa, kuti uwane mhedzisiro yekudzikisa huremu hwemotokari.Asi dambudziko rinounzwa neizvi nderekuti michina yemidziyo inodzikirawo.Naizvozvo, kuitira kuti ive nechokwadi chemichini zvivakwa pasi peyakaderera-density mamiriro, magirazi fibers anogona kushandiswa kupa yakakwira michina mamiriro.Zvigadzirwa zveSMC zvataurwa pamusoro zvinoumbwa negirazi fiber, filler uye resin.
Girazi fiber zvigadzirwa zveSMC zvine simba rakawanda uye pamusoro pezvivakwa.Chigadzirwa chacho chinogona kusangana nezvinodiwa zvema mechanical zvivakwa uye A-level pamusoro pezvivakwa panguva imwe chete, uye yakakodzera kugadzirwa kwemotokari kutaridzika zvikamu uye zvimiro.Kuenzaniswa nevakwikwidzi veindasitiri pasi pemamiriro akafanana, iyo yese mechanical performance yakawedzera ne20%, iyo inopa mhinduro kune yakaderera-density SMC mechanical performance degradation.
Kufanana neaya anovimbika emhando yepamusoro mota dzemitambo, izvo zvinodikanwa zvesimba uye chitarisiko zvakakwirira zvakanyanya kupfuura zvakajairika mota, kunyanya kutaridzika uye kutsetseka.SMC inoshandisa girazi fiber 456 semhando nyowani yegirazi faibha chigadzirwa chemotokari zvikamu, izvo zvinogona kusangana nemutengi A-level nzvimbo, kureva, girazi pamusoro pezvinodiwa, uye kupenya kwayo kunokwana kuenderana nekumisikidzwa kwema supercars.

Pamusoro pezvigadzirwa zveSMC, girazi fiber-yakasimbiswa thermoplastic zvinhu zvinogona zvakare kuita basa rakakosha mumunda wekutsiva simbi nepurasitiki mumotokari.Yepamusoro-inoshanda LFT yarn 362H inonyanya kushandiswa muzvikamu zvemotokari senge magirazi ekumashure, mavhavha asinganzwi, mabhureki ezviridzwa, nezvimwe.
LFT tekinoroji ine zvakakwirira zvinodikanwa pakugadziriswa kweshinda, kunyanya kupfeka kuramba kweshinda.Hubvudzi pakirogiramu ye362H yakaderera zvikuru.Dr. Fan Jiashu veChigadzirwa R&D Center vakasimbisa izvi kuburikidza nekuyedza kuenzanisa.Paakaisa humidity kusvika ku50%, bvudzi pakirogiramu ye362H yakanyanya kuderera pane iyo yekuenzanisa chigadzirwa;kana hunyoro hukakwira kusvika 75%, vhudzi rezvigadzirwa zvese rinowedzera, iro rinotemerwa nehunhu hweiyo saizi agent yeshinda pachayo.Asi zvinoshamisa ndezvokuti kana hunyoro huri 75%, vhudzi re 362H richiri rakaderera pane iro reboka rekutonga, rinoratidza zvakanakisa abrasion resistance ye362H.
Kwete izvozvo chete, iyo mechanical properties ye 362H inewo simba rakakwirira uye yakakwirira kuoma.Nayo, motokari ichava yakanyanya kutsungirira kuputsika kana kukanganisa kwakanyanya kunoitika.Izvo hazvizove se "brittle" sesimbi, uye hazvizove nyore "kukuvadzwa".Izvi zvakafanana nepamusoro pe362H.Iyo yakasarudzika saizi mumiriri kurapwa haiparadzaniswe.Iko kuvandudzwa kwepamusoro-kugadzira uye kushanda kwepamusoro LFT-yakawedzera shinda yakananga yePP 362H inowedzera kuvandudza chigadzirwa chechigadzirwa cheshinda yakananga yeLFT.Kupararira kwayo kwepamusoro uye mafuta akawandisa anosangana nezvinodiwa nemutengi kuti zvigadziriswe.
