Plasticizers yog hom tshwj xeeb ntawm additives. Tsis muaj plasticizers , feem ntau ntawm cov txhaj tshuaj molding Cov tebchaw yuav tsis haum rau lub hom phiaj ntawd, thiab qee qhov sib xyaw ntawm cov roj hmab yuav tsis raug tsim tawm ntawm tag nrho. Plasticizers ua yas elastic, extensible, yoog raws, thiab yas ntawm qhov kub thiab txias.

Kuj paub yog, lub hom phiaj ntawm plasticizers yog dab tsi?

Plasticizers yog siv los hloov PVC, cov yas tawv tawv, rau hauv cov khoom muag muag, hloov tau, thiab elastic. A yas yas uas yog sib xws nrog PVC thiab ua pov thawj tsis tshua muaj volatility, zoo permanence, thiab high efficiency yog xa mus rau ib tug thawj. yas yas.

Tom qab, lo lus nug yog, dab tsi plasticizers siv hauv PVC? Plasticizers rau plastics yog additives, feem ntau phthalate esters nyob rau hauv PVC daim ntawv thov. Yuav luag 90% ntawm plasticizers yog siv hauv PVC , muab cov khoom no txhim kho yooj thiab durability. Feem ntau yog siv nyob rau hauv cov yeeb yaj duab thiab cables.

Vim li cas cov plasticizers ntxiv rau polymers?

Plasticizers nce qhov ntws thiab thermoplasticity ntawm a polymer los ntawm kev txo cov viscosity ntawm cov polymer yaj, lub iav hloov pauv kub (Tg), qhov kub thiab txias (Tm) thiab elastic modulus ntawm cov khoom tiav yam tsis hloov pauv cov yam ntxwv ntawm cov tshuaj lom neeg. plasticized khoom.

Dab tsi yog plasticizers nrog piv txwv?

Ob qhov zoo piv txwv ntawm phthalate plasticizers yog DEHP (Di-Ethylhexyl Phthalate), thiab DINP (Di-Isononyl Phthalate). DEHP tau siv ntau tshaj plaws, thiab tseem yog yas yas ntawm kev xaiv rau tag nrho cov PVC kho mob thiab phais cov khoom.
