"Kuomarara" zvinoreva huwandu hwesimba rinodiwa kuti chinhu chigadzurwe; "Kuomarara" zvinoreva huwandu hwekuchinja kwechinhu chiri pasi pesimba reyuniti. "Kuomarara" kwakakura, kuchinja kushoma kunogona kuitika; "kuomarara" kwakakura, ndiko kunowedzera mukana wekushanduka. Chinhu chine kusimba kwakanaka chakapfava, uye kureba kwekuomarara pakuputsika uye simba rekudonha kwakakura, nepo kuomarara, simba rekuomarara uye modulus yekuomarara yekudhonza zvakaderera.
Sezvatinoona kubva patsananguro iri pamusoro apa, kuomarara nekusimba zvakasiyana, asi pamapurasitiki akagadziriswa anoenderana. Semuenzaniso, kana mapurasitiki akasimbiswa nefiberglass akava akaomarara, simba rekudhonza uye simba rekubaya zvinogona kuwedzera.
Nzira yekuvandudza kusimba kwepurasitiki?
Zvakaonekwa kuti kuwedzera kusimba kwe matrix resin kunogona kuvandudza simba rekusimba kwepurasitiki dzakasimba.
Kune nzira dzakawanda dzekusimbisa, dzakadai sekuwedzera huremu hwemamorekuru e matrix resin kuti ideredze kugoverwa kwehuremu hwemamorekuru, kana kudzora kugadzika kwekristaro, kristaro, saizi yekristaro uye chimiro chekristaro kuti ivandudze kusimba kwayo.
Nzira yekusiyanisa sei chinhu chinowanzo shandiswa pakugadzira purasitiki?
• Rabha elastomer yakasimba
EPR (binary ethylene-propylene), EPDM (EPDM), butadiene rabha (BR), natural rabha (NR), isobutene rabha (IBR), nitrile rabha (NBR), nezvimwewo. Yakakodzera kugadzirisa resin yepurasitiki;
• Ma elastomer e thermoplastic akasimba
SBS, SEBS, POE, TPO, TPV, nezvimwewo. Pakusimba kwepolyolefin kana kwete polar resin, papolyester, polyamide nedzimwe polima dzine mapoka anoshanda epolar, kusimba kunofanirwa kuwedzerwa zvinopindirana;
• Copolymer yepakati peganda yakakamurwa uye terpolymer inopindura
ACR (acrylate), MBS (methyl acrylate-butadiene-styrene copolymer), PTW (ethylene-butyl acrylate-glycidyl methacrylate copolymer), E-MA-GMA (ethylene-methyl acrylate-glycidyl methacrylate copolymer), nezvimwewo. Inoshandiswa pakugadzira mapurasitiki uye kugadzirisa polymer alloy inodzivirira kupisa kwakanyanya;
• Inosimbiswa nekusanganisa mapurasitiki akasimba
PP/PA, PP/ABS, PA/ABS, HIPS/PPO, PPS/PA, PC/ABS, PC/PBT, nezvimwewo. Tekinoroji yepolymer alloy inzira yakakosha yekugadziriramapurasitiki einjiniya ekusimba kwakanyanya.
• Dzimwe nzira dzekusimbaradza
Kusimbaradza kwe nano-particles (senge nano-cacO3), kusimbaradza sarin resin (Dupont metal ionomer), nezvimwewo.
Zviri Mukati
Nemakore anoda kusvika makumi maviri ari muindasitiri yemidziyo yekuwedzera zvinhu zvine hungwaru, akabata mabasa akakosha kuJwell Machinery, kusanganisira General Manager uye Rotating Chairman. Kubva muna 2024, anga achitungamira makambani akawanda, achitungamira kukura kwebhizinesi nekuvandudza maindasitiri, ukuwo achitungamira hunyanzvi mukugadzira zvinhu zvine hungwaru uye kukura kwepasi rose.
