1. Isishwankathelo seSicelo noLungiselelo:
Izinto ezikhethekileyo zokugquma i-polypropylene zisetyenziselwa ukugquma kwepolypropylene ibhegi ephothiweyo kunye nelaphu elilukiweyo. Emva kokugquma, iingxowa ezilukiweyo ezenziwe ngengubo zinokusetyenziswa ngokuthe ngqo ngaphandle kweengxowa ze-polyene. amandla kunye nokusebenza ngokubanzi kwesikhwama esilukiweyo kuphuculwe kuba ifilimu yokujikeleza i-polypropylene ifakwe ngokuthe ngqo kwisikhwama esilukiweyo, kwaye ukusetyenziswa kulungele, kunye neendleko zokuvelisa nazo ziyancitshiswa.

I-Arhente yeZixhobo zoKwakha kaRhulumente (i-National Building Materials Bureau) yaseka la magama & lt;1997>No.079 ngoNovemba 1997, imisela ukuba iingxowa eziphothiweyo eziphothiweyo mazisetyenziselwe ukupakishwa kwesamente nezinye iimveliso. Kwangaxeshanye, kunye nophuhliso lweshishini lokupakisha lwasekhaya, uluhlu lokusetyenziswa kunye nethamo lomgangatho wepeyinti wePP ngokuthe ngcembe lwandiswa. Umenzi weplastiki wokuqala uthenge umgca wemveliso weplastiki kunye neengxowa ezilukiweyo ezilukiweyo, ezitshintshiweyo ukusuka kwingxowa yangaphakathi ye-PE ye-PP ephothiweyo ukuya kwisingxobo esisigqubuthelo sesibini-kwisinye kunye nebhegi ehlanganisiweyo yeplastiki yephepha, kunye nemfuno yentengiso yebakala. I-PP iyanda imihla ngemihla. Unikezelo lwePP lwasekhaya lwepeyinti luqinile.
sinikwe oku ngasentla, sisekelwe kwi-T30S jikelele kunye ne-2401 (MFR = 2 ~ 4 g / 10min) kwaye siphuhlise ngempumelelo izinto ezikhethekileyo zebakala lokugubungela (MFR = 20 ~ 32 min, amandla okuqina 24.0 MPa) ngokuthotywa okulawulwayo emva kokuxuba.

Ngethuba lenkqubo yophuhliso, iimvavanyo ezininzi zenziwa ekukhethweni kwabalawuli be-molecular weight regulators kunye nezinye izinto ezincedisayo, ukuxuba kunye neplastiki yezinto eziluhlaza kunye neeparitha zenkqubo ehambelanayo. Emva kokuhlolwa okuphuculweyo, ukuqulunqwa kunye nenkqubo yokuveliswa kweengubo zePP zagqitywa. yenza umgca wokuvelisa ngobuninzi. iziphumo ezanelisayo zifunyenwe ngezicelo ezininzi, ezihlala zibonisa umgangatho ozinzile wemveliso, i-melt melt fluidity, ukubunjwa kwefilimu efanayo, i-shrinkage ephantsi, amandla aphezulu e-peel kunye nokunamathela okuphezulu. 2. Iinzuzo zoqoqosho eziqikelelwayo:

Ixabiso lezinto ezikhethekileyo ngetoni nganye yokugquma imalunga ne-2,000 yuan ngaphezulu kwexabiso lezinto eziluhlaza. Emva kokutsalwa kwezixhobo, abasebenzi, izinto eziluncedo, ukuhla kwexabiso koomatshini kunye nezinye iindleko ze-yuan ezili-150, inzuzo eseleyo ngetoni nganye yezinto ezikhethekileyo yi-yuan eyi-1500. Imveliso yonyaka yomgca wemveliso (ibalwe yi-extruder ene-screw diameter ye-65) yi-350-450 yeetoni, kwaye irhafu yonyaka yerhafu inokufikelela ngaphezu kwe-500000 yuan. ukuba usebenzisa i-screw extruder enkulu, imveliso iphezulu. Okwangoku, i-China ineefektri ezinkulu ezilukiweyo ezingaphezu kwe-1000, iilali kunye needolophu kunye namashishini abucala amaninzi. Iprojekthi inamathemba abanzi.
Okwesibini, iteknoloji yokulungiselela i-polypropylene yokupholisa i-masterbatch ye-polypropylene yokupholisa i-masterbatch yi-polypropylene-based masterbatch, isetyenziselwa ukunciphisa ubushushu bepolypropylene ukujikeleza kunye neemveliso zeplastiki ekuqhubeni, ngokukodwa kwi-polypropylene ejikelezayo isiphumo esihle kakhulu, kodwa ikwasetyenziswa kwimveliso yokuvuthela i-polypropylene. ifilimu, iingxowa zelaphu, i-monofilament, iimveliso zokubumba inaliti nazo zifumene iziphumo ezilungileyo.
isalathiso esiphambili sokusebenza: yongeza i-1 ~ 5% yokupholisa i-masterbatch kwi-polypropylene resin ukuze iqhutywe; inokufezekisa la manqaku alandelayo: onke amabanga e-polypropylene resin anokuvelisa umgangatho ophezulu we-C ojikelezayo we-fibre denier fiber. Iqondo lobushushu lokusonta kunye neplastiki linokucuthwa ukusuka kwi-20°C ukuya kuma-50°CC; ukuphucula umgangatho we-polypropylene fiber kunye neemveliso zeplastiki; ukuphucula impumelelo yemveliso; kunye nokunciphisa ukungcoliseka kwendalo.

Ubungakanani besicelo: i-polypropylene spinning, ifilimu ye-polypropylene evuthela, iingxowa ezilukiweyo ezine-polypropylene, i-monofilament
