1. Gusaba no Gutegura Imyanzuro:
Ibikoresho byihariye byo gutwika polypropilene bikoreshwa cyane cyane mugutwikira umufuka wa polypropilene hamwe nigitambara. Nyuma yo gutwikira, imifuka iboshywe ikozwe mu mwenda irashobora gukoreshwa mu buryo butaziguye nta mifuka ya polyene. imbaraga nibikorwa rusange muri rusange umufuka uboshywe uratera imbere kuko firime ya polipropilene ikwirakwizwa neza ku mufuka uboshye, kandi gukoresha biroroshye, kandi ikiguzi cyo gukora nacyo kiragabanuka.

Ikigo cya Leta gishinzwe ibikoresho (Ikigo cy’igihugu gishinzwe ibikoresho byubaka) cyashyizeho amagambo & lt; 1997> No.079 mu Gushyingo 1997, giteganya ko imifuka iboheye igomba gukoreshwa mu gupakira sima n’ibindi bicuruzwa. Muri icyo gihe, hamwe niterambere ryinganda zipakira murugo, imikoreshereze yimibare hamwe na dosiye yo murwego rwo gusiga irangi PP yagutse buhoro buhoro. Uruganda rukora plastike rwambere rwaguze umurongo wibikorwa bya pulasitike nububoshyi bukomatanyije, byahinduwe biva mumufuka wambere PE wimbere PP umufuka wububiko uhinduka umufuka wibiri-umwe-umwe hamwe nimpapuro eshatu-imwe-imwe yimifuka ya pulasitike, hamwe nisoko ryamasoko PP iriyongera umunsi kumunsi. Urwego rwo gusiga irangi murugo PP irakomeye.
ukurikije ibyavuzwe haruguru, twashingiye kuri rusange T30S na 2401 (MFR = 2 ~ 4 g / 10min) kandi tunatezimbere neza ibikoresho byihariye byo murwego rwo hejuru (MFR = 20 ~ 32 min, imbaraga zingana 24.0 MPa) binyuze mubitesha agaciro nyuma yo kuvanga.

Mugihe cyiterambere, hakozwe ubushakashatsi bwinshi kubijyanye no gutoranya ibipimo ngororamubiri bya molekuline nibindi bikoresho, kuvanga no gutunganya plastike y'ibikoresho fatizo hamwe n'ibipimo bifitanye isano. Nyuma yo gusuzuma neza, hashyizweho uburyo bwo gukora no gutunganya ibicuruzwa bya PP. gukora umurongo rusange. ibisubizo bishimishije byabonetse binyuze mubikorwa byinshi, burigihe byerekana ubuziranenge bwibicuruzwa, amazi meza ashonga, gukora firime imwe, kugabanuka gake, imbaraga zishishwa ryinshi hamwe no gufatira hejuru. 2. Inyungu ziteganijwe mu bukungu:

Igiciro cyibikoresho bidasanzwe kuri toni yikingirizo ni hafi 2000 yuan hejuru yikiguzi cyibikoresho fatizo. Nyuma yo gukuramo ibikoresho, umurimo, ibikorwa, guta agaciro kwa mashini nandi yakoreshejwe angana na Yuu 150, inyungu yunguka kuri toni yibikoresho byihariye ni 1500. Umusaruro wumwaka wumurongo wibikorwa (ubarwa na extruder ufite diameter ya screw ya 65) ni toni 350-450, kandi umusoro wumwaka urashobora kugera kumafaranga arenga 500000. niba ukoresheje screw nini ya extruder, umusaruro ni mwinshi. Kugeza ubu, Ubushinwa bufite inganda nini zirenga 1000 zikozwe mu mifuka, imidugudu n’imijyi ndetse n’ibigo byigenga bitabarika. Umushinga ufite icyerekezo kinini.
Icya kabiri, tekinoroji yo gutegura polypropilene gukonjesha masterbatch polypropylene gukonjesha masterbatch ni igishushanyo mbonera gishingiye kuri polypropilene, gikoreshwa cyane cyane kugabanya ubushyuhe bwizunguruka rya polypropilene nibicuruzwa bya pulasitike mugutunganya, cyane cyane mubizunguruka bya polipropilene, ariko bikoreshwa no mubikorwa bya polypropilene firime, imifuka yimyenda, monofilament, ibicuruzwa byo gutera inshinge nabyo byakiriye ibisubizo byiza.
indangagaciro nyamukuru: ongeraho 1 ~ 5% gukonjesha masterbatch kuri polypropilene resin yo gutunganya; Irashobora kugera ku ngingo zikurikira: amanota yose ya polypropilene resin irashobora gutanga ubuziranenge bwa C buzengurutse fibre nziza. Ubushyuhe bwo kuzunguruka no gutunganya plastike burashobora kugabanuka kuva kuri 20 ° C kugeza kuri 50 ° CC; kuzamura ubwiza bwa fibre polypropilene nibicuruzwa bya plastiki; kuzamura umusaruro; no kugabanya kwanduza ibidukikije.

Igipimo cyo gusaba: kuzunguruka polypropilene, firime ya polypropilene ihuha, imifuka iboshye ya polypropilene, monofilament
