Plastics tsis tuaj yeem hloov cov ntaub ntawv hlau, tab sis ntau yam khoom ntawm plastics tau dhau los ntawm cov alloys.Thiab daim ntawv thov ntawm cov yas tau tshaj cov hlau, cov yas tuaj yeem hais tau zoo rau peb lub neej.Cov tsev neeg yas tuaj yeem nplua nuj thiab muaj rau ntau hom yas, cia peb nkag siab lawv.
1. Cov khoom siv PC
PC muaj cov pob tshab zoo thiab cov thermal stability.Qhov tsis zoo yog tias nws tsis hnov zoo, tshwj xeeb tshaj yog tom qab siv lub sijhawm, cov tsos zoo li "qhuav", thiab nws tseem yog cov yas yas, uas yog, plexiglass, xws li polymethyl methacrylate., polycarbonate, thiab lwm yam.
PC yog cov khoom siv dav siv, xws li cov xov tooj ntawm tes, laptops, thiab lwm yam, tshwj xeeb tshaj yog rau kev tsim cov mis nyuj, khob qhov chaw, thiab lwm yam.Cov me nyuam lub raj mis tau muaj teeb meem nyob rau xyoo tas los no vim tias lawv muaj BPA.Residual bisphenol A nyob rau hauv PC, qhov kub thiab txias, tso tawm ntau dua thiab ceev ceev.Yog li ntawd, PC dej fwj yuav tsum tsis txhob siv los tuav dej kub.
2. Cov khoom siv PP
PP yas yog isotactic crystallization thiab muaj thermal stability, tab sis cov khoom yog nkig thiab yooj yim tawg, feem ntau yog cov khoom siv polypropylene.Lub thawv noj su microwave yog ua los ntawm cov khoom siv no, uas tiv taus qhov kub thiab txias ntawm 130 ° C thiab tsis pom zoo.Qhov no yog tib lub thawv yas uas tuaj yeem muab tso rau hauv lub qhov cub microwave thiab tuaj yeem rov qab siv tau tom qab ua tib zoo tu.
Nws yuav tsum raug sau tseg tias, rau qee lub thawv noj su hauv microwave, lub thawv lub cev yog ua los ntawm No. 05 PP, tab sis lub hau yog ua los ntawm No. 06 PS (polystyrene).Lub pob tshab ntawm PS yog qhov nruab nrab, tab sis nws tsis tiv taus qhov kub thiab txias, yog li nws tsis tuaj yeem ua ke nrog lub thawv lub cev.Muab tso rau hauv lub microwave.Yuav kom nyob rau sab nyab xeeb, tshem lub hau ua ntej muab lub ntim rau hauv lub microwave.
3. Cov khoom siv PVC
PVC, tseem hu ua PVC, yog polyvinyl chloride resin, uas feem ntau yog siv los ua engineering profiles thiab niaj hnub lub neej cov khoom yas, xws li raincoats, tsev cov ntaub ntawv, yas films, yas thawv, thiab lwm yam zoo heev plasticity thiab tsis muaj nqi.Tab sis nws tsuas tuaj yeem tiv taus qhov kub ntawm 81 ℃.
Cov tshuaj lom thiab teeb meem uas cov khoom yas ntawm cov khoom no yog tsim los ntawm ob yam, ib qho yog monomolecular vinyl chloride uas tsis yog polymerized tag nrho thaum lub sij hawm tsim khoom, thiab lwm yam yog cov teeb meem tshuaj nyob rau hauv lub plasticizer.Ob yam khoom no yooj yim rau precipitated thaum ntsib qhov kub thiab txias.Tom qab cov tshuaj lom neeg nkag mus rau tib neeg lub cev nrog zaub mov, nws yooj yim ua rau mob qog noj ntshav.Tam sim no, ntim cov khoom siv no tsis tshua muaj siv los ntim khoom noj.Tsis tas li ntawd, tsis txhob cia nws kub.
4. Cov khoom siv PE
PE yog polyethylene.Cling zaj duab xis, yas zaj duab xis, thiab lwm yam yog tag nrho cov khoom no.Lub tshav kub kuj tsis muaj zog.Feem ntau, cov ntaub qhwv yas PE tsim nyog yuav muaj qhov tshwm sim kub yaj thaum qhov kub siab tshaj 110 ° C, tawm hauv qee qhov kev npaj yas uas tsis tuaj yeem decomposed los ntawm tib neeg lub cev.
Tsis tas li ntawd, thaum cov zaub mov raug cua sov los ntawm kev qhwv lub hnab yas, cov roj hauv cov zaub mov tuaj yeem yooj yim yaj cov khoom tsis zoo hauv cov ntaub qhwv yas.Yog li ntawd, thaum cov zaub mov muab tso rau hauv lub qhov cub microwave, lub hnab yas qhwv yuav tsum tau muab tshem tawm ua ntej.
5. Cov khoom siv PET
PET, uas yog, polyethylene terephthalate, lub raj mis dej ntxhia thiab lub raj mis carbonated yog txhua yam ua los ntawm cov khoom siv no.Cov fwj dej haus tsis tuaj yeem siv dua los tuav cov dej kub.Cov khoom no yog kub-resistant rau 70 ° C thiab tsuas yog haum rau sov los yog khov dej qab zib.Nws yog ib qho yooj yim rau deform thaum sau nrog cov kua kub kub los yog rhuab, thiab muaj cov khoom uas muaj teeb meem rau tib neeg lub cev.
6. Cov khoom siv PMMA
PMMA, uas yog, polymethyl methacrylate, tseem hu ua acrylic, acrylic lossis plexiglass, yog hu ua compressive force hauv Taiwan, thiab feem ntau hu ua agaric kua nplaum hauv Hong Kong.Nws muaj cov pob tshab siab, tus nqi qis, thiab kev ua haujlwm yooj yim.thiab lwm yam zoo, nws yog ib qho khoom siv iav hloov khoom siv.Tab sis nws cov cua kub tsis kam yog siab, tsis muaj tshuaj lom.Nws yog dav siv nyob rau hauv lub advertising logo ntau lawm kev lag luam.
