PVC muaj ntau yam khoom zoo heev thiab siv dav, tab sis nws lub zog cuam tshuam, lub zog cuam tshuam qis hauv qhov kub thiab txias, thiab lwm yam khoom cuam tshuam tsis zoo tag nrho. Yog li ntawd, yuav tsum ntxiv cov khoom hloov pauv cuam tshuam kom hloov qhov tsis zoo no. Cov khoom hloov pauv cuam tshuam feem ntau suav nrog CPE, ABS, MBS, EVA, SBS, thiab lwm yam. Cov neeg sawv cev tawv ua rau cov yas tawv dua, thiab lawv cov khoom siv kho tshuab yog cov yam ntxwv los ntawm cov khoom flexural thiab tensile, es tsis yog kev tiv thaiv cuam tshuam.
Cov khoom ntawm CPE muaj feem cuam tshuam nrog cov ntsiab lus chlorine. Ib txwm muaj, CPE uas muaj 35% chlorine tau siv vim nws muaj cov roj hmab zoo dua thiab sib xws zoo heev. Tsis tas li ntawd, cov khoom siv cua sov PVC ib txwm kuj tseem siv tau rau CPE yam tsis tas yuav ntxiv lwm cov khoom siv tshwj xeeb. MBS, zoo ib yam li ABS, muaj kev sib xws zoo nrog PVC thiab tuaj yeem siv ua cov khoom hloov pauv rau PVC. Txawm li cas los xij, hauv ABS thiab MBS formulations, vim lawv tsis tiv taus huab cua, feem ntau ntawm lawv siv rau cov khoom siv hauv tsev, thiab MBS tuaj yeem siv rau cov khoom semi pob tshab rau cov khoom pob tshab.
Peb lub tuam txhab tsom mus rau kev tshawb fawb thiab kev txhim kho, kev tsim khoom, thiab kev muag khoom ntawm cov khoom hloov kho yas PVC. Cov khoom uas lub tuam txhab tsim tawm feem ntau suav nrog ACR impact processing modifier, MBS impact modifier, thiab chlorinated polyethylene, uas siv tshwj xeeb los txhim kho kev ua haujlwm, lub zog cuam tshuam, thiab qhov kub qis ntawm kev ua cov yas PVC. Cov khoom ntawm lub tuam txhab siv dav hauv cov teb xws li cov kav dej, cov ntaub ntawv tsim kho, kev txhaj tshuaj molding, cov khoom siv tshuab pwm, thiab lwm yam.
Nyob rau xyoo tas los no, lub tuam txhab kev nqis peev hauv kev tshawb fawb thiab kev txhim kho cov roj hmab thiab ABS additives thiab thev naus laus zis tau nce ntxiv txhua xyoo. Txawm hais tias tag nrho thiab kev siv zog ntawm kev tshawb fawb thiab kev txhim kho kev nqis peev tau tswj hwm ob qho kev loj hlob, cov qauv ntawm kev tshawb fawb thiab kev txhim kho kev nqis peev tau raug kho kom zoo. Hais txog kho vajtse, lub tuam txhab tau yuav cov kab tsim khoom thoob ntiaj teb thiab cov khoom siv kuaj mob siab heev, cog lus tias yuav tsim cov khoom nrog cov qib siab thoob ntiaj teb. Cov khoom siv raw uas xav tau rau kev tsim khoom kuj tau yuav los ntawm cov tuam txhab tsim khoom siv thev naus laus zis thoob ntiaj teb, nrog kev ruaj khov thiab txhim khu kev qha zoo. Tam sim no, lub tuam txhab muaj 5 tus neeg ua haujlwm R & D laus, ntau dua 20 tus neeg ua haujlwm R & D nruab nrab, thiab ntau dua 20 pab pawg sib koom tes. Lub tuam txhab tau koom tes tsim cov khoom tshiab nrog cov tuam txhab txawv teb chaws paub zoo, uas tuaj yeem daws cov teeb meem ntawm cov khoom xyaw yas ib txwm muaj thiab cov nqi siab, thiab tau ua tiav cov txiaj ntsig zoo.
