1. Cov huab cua dav dav
Feem ntau hais txog plastics nrog cov zis loj, dav daim ntawv thov, muaj kev tsim zoo thiab tus nqi qis. Muaj tsib tus loj hom kev dav dav, uas yog polyethylene (PE), polypropylene (ptfinyl chloride (PTFE), psstyrene (ps) thiab ABS. Lawv txhua tus thermoplastics.
2. Engineering plastics
Feem ntau hais txog cov plastics uas tuaj yeem tiv taus qee yam khoom sab nraud, muaj cov kws kho tshuab ua kom zoo, thiab cov tshuab ua kom zoo dua qub, thiab cov tshuab ua kom zoo nkauj plastics thiab tshwj xeeb engineering plastics.
Kev tsim kho kom haum, Polyychamethylene, etcoprice polyester, ultra-siab engineing capolymer tau muab faib ua ke thiab cov hom no tsis muaj sib txuas. Cov kab ntoo khaub lig-txuas muaj xws li: polyaminobismaleamide, polytriazine, raset sulfide epoxy, polyether sulfide, polyether ether ether ketone (peet ether ketone (peet ether ketone (peet
3. Cov ntaub ntawv tshwj xeeb
Feem ntau hais txog plastics nrog cov haujlwm tshwj xeeb uas tuaj yeem siv rau hauv cov ntawv thov tshwj xeeb xws li Aviation thiab Aerospace. Piv txwv li, fluoropoplastics thiab silicones muaj cov haujlwm tshwj xeeb zoo xws li cov khoom siv kub siab thiab ua npuas dej muaj cov khoom tshwj xeeb xws li siab lub zog thiab lub siab tawv. Cov plastics txhua lub zwm rau qeb ntawm tshwj xeeb. Lawv muab faib ua kom muaj zog thiab ua npuas ncauj ua npuas ncauj.
2. Kev faib tawm los ntawm lub cev thiab tshuaj
Raws li lub cev sib txawv thiab tshuaj lom neeg ntawm ntau cov yas plastics, cov plastics tuaj yeem faib ua ob hom: thermosetting plooj thiab thermoplastic plastics.
1. Thermoplastic plastics
Qhov ntsuas hluav taws xob plastics defastics uas tuaj yeem faib cov hom xim zoo nkauj, thiab lwm yam. Polytetrafluoroethylene (PTFE), polystyrene (PS). Polyethylene (PE) thiab polypropylene (PP) Txhua yam muaj dielectric tsis tshua muaj thiab dielectric poob, thiab haum rau cov khoom siv hluav taws xob ntau thiab cov khoom siv hluav taws xob siab.
Formaldehyde hla cov plastics suav nrog phenolic plastics thiab amino plastics (xws li urea-formaldehyde-methyyde, thiab lwm yam). Lwm cov ntoo khaub lig-txuas nrog cov txheej txheem tsis txaus ntseeg, Epoxy Resins, thiab dially philalate resins.
2. Thermosetting dub
Thermosetting drastics xa mus rau plastics uas tuaj yeem ua kom haum, thiab lwm yam) fermoyde nyob rau hauv ob hom: formatdehyde hom thiab lwm hom cross-txuas.
Cov thermosetting plooj ntub suav nrog phenolic, amino, polyerilicone thiab lwm yam ntaub ntawv, nrog rau Polypropylene phthaltics.
Qee qhov plastics yog ob qho nyuaj thermoplastic thiab thermosetting plastics. Piv txwv li, polyvinyl tshuaj chloride feem ntau yog cov thermoplastic yas.
① Ntsug qhov uas muaj tseeb. Lawv tsis yog-polar plastics, uas tau muab faib ua crystalline thiab tsis-crystalline. Crystalline hloov cov yas xws li polyethylene xws li polyethylene, polypropylene, thiab lwm yam, thiab tsis yog-crystalline sib piv kom muaj polystyrene, thiab lwm yam.
In Vinyl plastics muaj polar noob. Tsuas yog fluoropleplastics, feem ntau yog tsis-crystalline lub cev, suav nrog polymeroTree, thiab lwm yam feem ntau ntawm Vinyl Monomers tuaj yeem siv dawb radical catalalysts.
③thermoplastic engineering plastics. Mas suav nrog polyoxymethylene, polyamide, polyphentry ether, polyethlide sulfide, thiab lwm yam polytetrosauruoroethylene. Hloov polypropylene, thiab lwm yam kuj muaj nyob hauv qhov no.
④ thermoplastic cellulose plastics. Feem ntau yog suav nrog cellulose acetate, cellulose acetate butetate butetate Butyrate, celluloid, cellulopane, cellonhane, thiab lwm yam.
Thaum peb ua xim xim masterbatch, peb yuav tsum paub txog cov ntaub ntawv siv thiab ua cov khoom siv los tsim cov xim masterbatch. Nws yog cov ntaub ntawv tseem ceeb heev.
