EPP yog kaw-cov ntaub ntawv xovtooj ntawm tes ua npuas dej ua rau kub thiab kub siab siv lub siab yaj polypropylene (HMSPP) ua cov matrix resin. Nws muaj cov thermal stability zoo heev, poob siab tsis kam, cuam tshuam lub zog thiab toughness, siab rov qab tus nqi tom qab deformation, 100% recyclable, kub-resistant, tshuaj-resistant thiab roj-resistant.
Nyob rau tib lub sijhawm, EPP yog cov carbohydrate ntshiab, tsis muaj cov khoom siv ntxiv xws li plasticizers thiab foaming agents, tsis muaj teeb meem thiab tsis muaj ntxhiab, muaj VOC emissions qis, thiab siv dav hauv kev lag luam xws li tsheb, ntim khoom, thiab cov khoom noj tshiab. Rwb thaiv tsev lub thawv ua los ntawm EPP cov ntaub ntawv zoo tagnrho rau pab pawg noj mov, zaub, zaub mov tshiab, khoom noj khov thiab lwm yam khoom xyaw kom sov thiab tshiab.
Dab tsi yog qhov zoo ntawm EPP?
Nrog kev nthuav dav txuas ntxiv ntawm cov kab mob khaub thuas sib faib khoom noj tshiab hauv kuv lub teb chaws, cov teeb meem ntawm " mais kawg" cov kab mob khaub thuas, cov kev lag luam ntim khoom lag luam cumbersome, thiab cov nqi siab ntawm cov tsheb thaiv hluav taws xob tau dhau los ua qhov tseem ceeb. Muaj kev nyab xeeb, noj qab nyob zoo, ib puag ncig tus phooj ywg, yooj yim thiab cov ntaub ntawv rwb thaiv tsev yog nyiam los ntawm tib neeg. EPP tau dhau los ua qhov nrov tshaj plaws ntawm ib puag ncig tus phooj ywg tshiab siab - cov khoom siv rwb thaiv tsev tiv thaiv nrog nws cov rwb thaiv tsev zoo tshaj.
Kev ua haujlwm zoo thermal rwb thaiv tsev
Thermal conductivity yog ib qho tseem ceeb qhia siv los ntsuas cov thermal conductivity thiab thermal rwb thaiv tsev kev ua tau zoo ntawm cov cua sov-cov ntaub ntawv resistant. Rau cov ntaub ntawv ntawm tib lub qauv, lub thickness nce, thermal rwb thaiv tsev kev ua tau zoo dua, thiab cov thermal conductivity yog me dua. Raws li qhov loj me, qhov thermal conductivity ntawm EPP yog qis dua li ntawm lwm cov ntaub ntawv foaming xws li PE thiab PU, thiab nws cov thermal rwb thaiv tsev ua tau zoo tshaj plaws.
EPP muaj zog nqus tau zoo. Thaum muaj kev cuam tshuam, cov micropores ntawm foamed polypropylene cell yog squeezed, thiab cov kev hloov nyob rau hauv lub ntim ntawm lub micropores ua rau lub deformation ntawm cov khoom ua npuas ncauj, yog li siv lub zog cuam tshuam, tiv thaiv cov khoom los ntawm kev puas tsuaj, thiab ua si ib tug zoo buffering lub luag hauj lwm. Lub micropores ntawm foamed polypropylene hlwb nrog cov ntom ntom sib txawv, thiab lub peev xwm buffering kuj txawv; Tsis tas li ntawd, lub thickness tseem yuav cuam tshuam rau nws cov dynamic buffering kev ua tau zoo
Safe nplaim retardant
Cov nplaim hluav taws zoo ib puag ncig- cov khoom siv hluav taws xob EPP npaj los ntawm kev hloov kho polypropylene nrog ib puag ncig tus phooj ywg nplaim hluav taws retardant thev naus laus zis muaj qhov tso tawm qeeb qeeb hauv hluav taws, ua pa taws tsawg dua, thiab tsis muaj kev phom sij. Nws cais cov hluav taws kub ntawm cov nplaim taws los ntawm sab nraud kom tsis txhob muaj hluav taws kub hnyiab, thiab tua hluav taws tam sim ntawd tsis muaj dej, tsis txhob kis hluav taws.
Kub thiab kub tsis kam
EPP muaj kev siv kub ntawm -40℃-130 degree, thiab nws qhov siab tshaj plaws siv kub yog ntau dua li 80℃siab tshaj plaws siv kub ntawm polyethylene ua npuas ncauj. Nws kuj tseem siv tau zoo nyob rau hauv qhov kub thiab txias ntawm -40 degree
Kev tiv thaiv nto zoo
EPP rwb thaiv tsev lub thawv thiab lwm yam khoom yog ib nrab- nruj ib - daim molding, nrog ib tug du nto, tshav ntuj-resistant, hnav-resistant, thiab rub-resistant, thiab yuav rov qab siv tau 1,000 zaug los yog ntau tshaj. Roj- pov thawj, tsis muaj dej, thiab tshuaj lom neeg- tiv taus, EPP cov khoom muaj cov qauv ruaj khov, tsis ntub los yog oily, thiab muaj kev tiv thaiv zoo rau cov tshuaj.
Rov ua dua
Cov ntaub ntawv EPP tuaj yeem siv rov ua dua tshiab rau cov nqi seem tom qab siv, thiab tuaj yeem siv rov ua dua tom qab kev kho degradation tsis muaj teeb meem, uas yog ib puag ncig tus phooj ywg thiab muaj kuab paug -dawb.
