Uncedo lokucubungula i-PVC lukhuthaza njani ukusebenza kokuthambisa?

Indima yezixhobo zokulungisa i-ACR ekucutshungulweni kwe-PVC ibonakala kakhulu ekukhuthazeni ukwenziwa kweplastiki, ukuphucula iipropati zokunyibilika, ukuphucula uzinzo lokucubungula, ukuphucula umgangatho wemveliso, kunye nokuphucula ukulungelelaniswa kwenkqubo ekhethekileyo.
1. Khuthaza ukwenziwa kweplastiki
I-ACR isebenzisana neetsheyini ze-PVC molecular ngokusebenzisa amaqela e-polar, inciphisa ukungqubana phakathi kwamasuntswana, ikhawulezisa ukunyibilika kweplastiki, inciphisa ixesha lokucubungula (njenge-ACR-201, enciphisa ixesha lokufakelwa kweplastiki ngemizuzwana engama-40-60), kwaye inokunciphisa ubushushu bokufakelwa kweplastiki nge-10-20 ℃ (kwiimodeli eziqulethe amaqela e-carboxylic acid).
2. Lungiselela ukusebenza kokunyibilika
Yonyusa amandla okunyibilika: Iitsheyini ezinde zemolekyuli zenza uthungelwano oluhambelanayo, lonyusa amandla okunyibilika ngama-300% (ACR-401), luthintela ukuqhekeka kokunyibilika kwe-extrusion (njengokwenzeka kwesikhumba seshark);
Phucula ukutyibilika: nciphisa ukunyibilika kwe-viscosity nge-10-15% kwaye uphucule ukusebenza kakuhle kokuzalisa ngamanani aphezulu okucheba.
3. Phucula uzinzo lokucubungula
Nqanda ubushushu obugqithisileyo bendawo, nyusa ubushushu bokuqala bokubola kobushushu bePVC ukusuka kwi-190 ℃ ukuya kwi-210 ℃, nciphisa ukuguquguquka kobushushu obunyibilikayo, kwaye wehlise i-torque nge-15-20% xa idityaniswe nezinto zokuthambisa (ACR-530).
4. Phucula umgangatho wemveliso
Ukususa iziphene zomphezulu ezifana namehlo eentlanzi kunye neempawu zokuhamba kwamanzi, kuphucula kakhulu ukuguda (njengomhlwa<3%, ukukhazimla okungaphezulu kwe-90%); Ukuphucula ukuqina kwempembelelo (ukwandisa amandla empembelelo yobushushu obuphantsi ngokuphindwe ka-5-10) kunye nokumelana nemozulu.
5. Xhasa iinkqubo ezikhethekileyo
Intsimi ekhupha amagwebu: Phucula amandla okunyibilika ukuze iimbobo zegwebu zifane kwaye zibe xinene;
Imveliso ecacileyo: i-PVC refractive index ehambelanayo (ACR-Z30 haze<3%);
Intsimi yezonyango: Nciphisa imvula (iimodeli eziqulethe amaqela e-carboxylic acid zinciphisa ukukhutshwa kwe-HCl ngama-60%).
Iimodeli ezahlukeneyo zifanelekile kwiinkqubo ezithile: I-ACR-401 (i-extrusion/rolling) iphucula amandla okunyibilika, i-ACR-201 (i-injection/blow molding) iphucula ukuhamba kwamanzi, i-ACR-530 ilinganisela inkqubo yokuthambisa.
