Iingcebiso eziphambili: I-PP inokuhlelwa ngokwee-substrates ezahlukeneyo, kwi-classification isenokuthi ihluke kwiinkcazo zezinga lokunyibilika, kwaye ngokuhambelana nokusetyenziswa kwezongezo kwiimpahla zomntu ngamnye ukugqiba ukusetyenziswa kwenkcazo.Ngokomzekelo, kwipolymer enye, I-MFR: I-12 okanye kunjalo ingasetyenziselwa ngokubanziiimveliso zokutofa, ingasetyenziselwa ukuveliswa kwemicu ye-multifilament, kwaye inokuveliswa ngokukodwa ukubonelela ngokusabalalisa ubunzima bemolekyuli ukuphucula icandelo elingasemva le-processability ye-fiber weaving.Ngexesha elifanayo, inokongeza i-agent sliding kunye ne-anti-adhesive agent. ukwandisa ukuvulwa ukuhlangabezana neemfuno zeibhegi yeplastikhiiimveliso.
1. Inqanaba ngokubanzi (Homopolymer)
I-monopolymer, okanye i-homopolymer, yimathiriyeli ekrwada apho ipropylene ecocekileyo yenziwa ipholymerized.
2. I-COPOLYMER enempembelelo
Xa i-polymer enye yongezwa ngerabha ye-ethylene propylene, amandla empembelelo ikakhulu axhomekeke kumxholo werabha, kunye nokumelana nokubanda kuxhomekeke kumxholo we-ethylene.
3. I-isotacites ephezulu okanye i-CRISTALLINITY HIGH
Ukunciphisa umxholo wokuchithwa kwesakhiwo kwi-polymer ye-PP, ukunyuka okuhambelanayo komxholo wesakhiwo esiqhelekileyo, kwakhona ukuphucula i-crystallinity.It ikakhulu iphucula ukuqina, ubushushu be-thermal denaturation, ubunzima bomhlaba, ukuchasana nokukrala kunye ne-gloss yezinto eziluhlaza. Kakade ke, ukongezwa kwe i-nucleating agent iya kuba negalelo ekwandiseni ezi mpawu zingentla.
4. I-COPOLYMER engaqhelekanga
I-copolymerization engahleliwe yipropylene kunye ne-ethylene copolymerization.I-ethylene ichithwa ngokungaqhelekanga kwipolymer, eyona nto inciphisa i-crystallinity ye-polymer kwaye iphucula ukucaca.
5. Terpolymer
Ngaba ukongezwa kwe-random ye-polymer, ngokubanzi iqulethe i-propylene ethylene (EPR) amanqanaba aphezulu kwi-3.5%, kodwa kukho inkqubo enokuthi ifakwe kwi-5%, kunye nomxholo ophezulu we-ethylene kwimveliso ethambileyo ngakumbi, ubushushu bokuguqulwa kwe-thermal, ukuthambisa. inqaku, iqondo elisezantsi ubushushu ukutywinwa ubushushu, ngamanye amaxesha ukuze kwandiswe ethylene umxholo ngoncedo butadiene okanye ezinye izithako wesithathu zibe iipolymer ezintathu eziqhelekileyo, ukuze kuzuzwe iimfuno zepropati emzimbeni ngasentla.
6. Ibakala lengxubevange
Umxube wezinto ezahlukeneyo zeplastiki ezinomlinganiselo ophezulu unokuchazwa njengebakala le-alloy.Ngokomzekelo, i-PP eyongeziweyo kunye ne-LDPE inokuphucula ukuthamba kunye namandla eempembelelo, kwaye inokunciphisa intamo kunye nokunyusa ukugudisa ekuqhubeni.Ekubumbeni, kunokunciphisa i-drop material phenomenon.PP kunye ne-EPR kunye ne-HDPE inokugcina ukuqina, ukunciphisa into emhlophe ebangelwa umxholo ophezulu we-EPR, kunye nokuphucula amandla empembelelo.
7.Ukudibanisa
Ukuxuba izinto ezahlukeneyo
