Polypropylene (PP)
Polypropylene yog ib yam khoom siv yas
Cov khoom siv kuj yog siv dav hauv kev txhaj tshuaj molding. Nws muaj cov yam ntxwv hauv qab no:
Cov khoom siv kho tshuab zoo: Polypropylene muaj lub zog siab thiab nruj, ua rau nws tsim nyog rau kev tsim cov khoom lag luam uas xav tau cov khoom siv tshuab siab.
Tshuaj tiv thaiv: Polypropylene muaj cov tshuaj zoo xws li kua qaub thiab alkali tsis kam, hnyav tsis kam, thiab lwm yam, ua rau nws ruaj khov rau kev siv ntau qhov chaw.
Zoo formability: Polypropylene yooj yim rau txheej txheem thiab muaj fluidity zoo, ua rau cov txheej txheem txhaj tshuaj smoother.
Tus nqi qis: Polypropylene yog cov khoom siv yas uas pheej yig, ua rau nws pheej yig dua hauv kev tsim khoom loj.
Polyethylene (PE)
Polyethylene yog lwm yam khoom siv yas thiab muaj ntau yam kev siv hauv kev txhaj tshuaj molding. Nws cov nta muaj xws li:
Zoo hnav tsis kam: Polyethylene muaj kev hnav zoo, ua rau nws tsim nyog rau kev tsim khoom lossis cov khoom uas yuav tsum tau hnav tsis kam.
Kev cuam tshuam zoo heev: Polyethylene muaj qee qhov toughness thaum raug cuam tshuam thiab tsis yooj yim tawg, ua rau nws tsim nyog rau kev tsim khoom uas yuav tsum tau muaj kev cuam tshuam.
Hluav taws xob rwb thaiv tsev zoo: Polyethylene muaj cov hluav taws xob rwb thaiv tsev zoo heev, ua rau nws siv dav hauv kev tsim cov khoom siv hluav taws xob hauv hluav taws xob thiab hluav taws xob.
Cov huab cua tsis zoo: Polyethylene muaj huab cua tsis zoo thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig sab nraud, ua rau nws tsim nyog rau kev tsim cov khoom siv sab nraum zoov.
Polystyrene (PS)
Polystyrene yog cov khoom siv pob tshab lossis semi pob tshab uas feem ntau siv hauv kev txhaj tshuaj molding los tsim cov khoom pob tshab lossis xim. Nws cov nta muaj xws li:
High transparency: Polystyrene muaj pob tshab zoo thiab tuaj yeem tsim cov khoom ntshiab thiab pob tshab.
Gloss nto zoo: Cov khoom siv polystyrene muaj qhov du thiab qhov zoo ntawm gloss.
Kev ua tau zoo: Polystyrene yog ib qho yooj yim rau txheej txheem thiab cov duab, thiab tuaj yeem tsim cov khoom nrog cov duab nyuaj.
Zoo molding stability: Cov txheej txheem polystyrene molding yog ruaj khov thiab tsis yooj yim rau deformation lossis shrinkage teeb meem.
Polycarbonate (PC)
Polycarbonate yog cov khoom siv hluav taws xob ua haujlwm siab uas feem ntau siv hauv kev txhaj tshuaj molding los tsim cov khoom uas xav tau lub zog siab thiab kub ua haujlwm. Nws cov nta muaj xws li:
Lub zog siab: Polycarbonate muaj lub zog siab thiab tuaj yeem tsim cov khoom muaj zog tensile thiab khoov zoo.
Kev tiv thaiv tshav kub zoo: Polycarbonate muaj cov cua sov zoo thiab tuaj yeem ua haujlwm ruaj khov ntawm qhov kub thiab txias.
Cov pob tshab zoo heev: Polycarbonate muaj cov pob tshab siab thiab tuaj yeem tsim cov khoom ntshiab thiab pob tshab.
Kev tiv thaiv huab cua zoo: Polycarbonate muaj huab cua tsis zoo thiab tsis yooj yim cuam tshuam los ntawm ib puag ncig sab nraud xws li ultraviolet rays.
Ntxiv nrog rau cov khoom siv yas uas tau hais los saum no, kuj tseem muaj ntau yam khoom siv yas siv hauv kev txhaj tshuaj molding, xws li polyester resin, polyvinyl chloride, thiab lwm yam. Cov ntaub ntawv yas sib txawv muaj cov yam ntxwv sib txawv, thiab xaiv cov khoom siv yas tsim nyog muaj qhov tseem ceeb. cuam tshuam rau kev ua tau zoo thiab cov khoom zoo. Nyob rau hauv cov txheej txheem txhaj tshuaj molding, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov khoom siv kho tshuab, tshuaj lom neeg, kev tiv thaiv huab cua, thiab lwm yam ntawm cov khoom raws li cov kev cai tshwj xeeb ntawm cov khoom, thiab xaiv cov khoom siv yas uas tsim nyog tshaj plaws los xyuas kom meej tias cov khoom tiav. qhov xav tau siv.
