Daim ntawv thov
PP (polypropylene) pas nrig yog cov khoom siv semi-crystalline uas sawv tawm vim nws qhov tshwj xeeb ua ke ntawm lub cev thiab cov khoom siv kho tshuab. Ib qho ntawm nws cov yam ntxwv tseem ceeb tshaj plaws yog nws qhov hardness thiab siab melting point, uas teev nws sib nrug los ntawm lwm yam ntaub ntawv xws li PE (polyethylene). Thaum homopolymer hom PP tuaj yeem ua nkig heev thaum raug kub siab tshaj 0 ° C, ntau cov khoom lag luam PP yog tsim los ua random copolymers lossis clamp copolymer nrog feem pua ntawm ethylene.
Random copolymer feem ntau muaj 1 txog 4% ethylene, thaum clamp copolymers muaj qhov sib piv ntau dua ntawm ethylene. Cov txheej txheem copolymerization no ua rau cov khoom siv PP nrog qis dua qhov kub thiab txias (100 ° C) piv rau homopolymer PP. Txawm hais tias cov khoom siv copolymer hom PP tej zaum yuav muaj qis dua pob tshab, gloss, thiab rigidity, nws nthuav tawm lub zog muaj zog. Raws li cov ntsiab lus ethylene hauv copolymer nce, tag nrho lub zog ntawm cov khoom PP kuj nce, ua rau nws muaj ntau yam kev xaiv rau ntau yam kev siv.
Lwm yam tseem ceeb ntawm PP yog nws Vicat softening kub, uas yog 150 ° C. Qhov no kub tsis kam, ua ke nrog cov khoom siv qib siab ntawm crystallinity, ua rau muaj qhov tawv tawv zoo heev thiab khawb tsis kam. Cov khoom no ua rau PP yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas muaj zog thiab tsis kam hnav thiab tsim kua muag yog qhov tseem ceeb.
Tsis tas li ntawd, PP paub txog nws qhov kev tiv thaiv ib puag ncig kev ntxhov siab tawg, uas yog ib qho teeb meem tshwm sim hauv ntau lwm yam ntaub ntawv. Qhov no ua rau nws muaj kev ntseeg siab rau kev siv nyob rau hauv ib puag ncig uas muaj tshuaj lom neeg, noo noo, lossis lwm yam kev ntxhov siab.
Ntxiv nrog rau nws cov khoom siv kho tshuab, PP kuj muaj cov txheej txheem zoo heev. Nws tuaj yeem ua tau yooj yim zoo li tus thiab tsim siv ntau yam kev tsim khoom, xws li txhaj tshuaj molding, extrusion, thiab tshuab moulding. Qhov kev ua tau zoo no, ua ke nrog nws lwm yam khoom, ua rau PP qhov kev xaiv nrov rau ntau yam kev siv, suav nrog ntim, khoom siv tsheb, thiab cov khoom siv.
Zuag qhia tag nrho, PP pas nrig yog cov khoom siv ntau yam thiab ruaj khov uas muaj kev sib xyaw tshwj xeeb ntawm lub cev thiab cov khoom siv kho tshuab. Nws lub siab melting point, zoo heev nto tawv thiab khawb tsis kam, thiab tsis kam mus rau ib puag ncig kev ntxhov siab tawg ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv. Txawm hais tias koj tab tom nrhiav rau cov khoom siv uas tuaj yeem tiv taus qhov kub thiab txias, tiv taus hnav thiab tsim kua muag, lossis ob qho tib si, PP pas nrig yog ib qho kev ntseeg tau thiab muaj ntau yam kev xaiv uas paub tseeb tias yuav ua tau raws li koj xav tau.
