PVC agbara paipu aise ohun elo
Awọn ohun elo aise paipu agbara PVC,
PVC fun paipu agbara, pvc resini fun paipu,
Paipu agbara PVC ati ọna igbaradi rẹ pẹlu awọn ohun elo aise wọnyi:
100 polyvinyl kiloraidi resini,
15-25 kalisiomu kaboneti;
5-10 oxide titanium,
4 ~ 8 iyipada ipa,
2-5 amuduro,
0.5-2 epo epo,
2 ~ 4 sepiolite
3 ~ 8 Aṣoju oniduro inorganic inorganic inorganic, retardant inorganic inorganic flame retardant lati toje earth hydroxide aluminiomu hydroxide Ọna igbaradi ti iṣuu magnẹsia hydroxide ati zinc borate
Ilana iṣelọpọ:
1) Fi calcium carbonate titanium oxide sinu resini kiloraidi POLYvinyl ki o si dapọ ni iyara giga fun 3-6min;2) Lẹhinna ṣafikun amuduro ipa modifier, lubricant sepiolite ati idapada ina eleto ti ko ni nkan sinu adalu.
Awọn iwọn otutu dapọ jẹ 100-110, ati akoko idapọ jẹ iṣẹju 10-15.Lẹhin ti a ti dapọ idapọpọ paapaa, a ti gbe adalu naa si alapọpo itutu agbaiye ni iyara kekere ti 40 ~ 50 fun awọn iṣẹju 3-5, ati nikẹhin sinu conical twin screw extruder ni 170 ~ 190 tube agbara ina ni idaduro ina to dara ati darí-ini
Polyvinyl Chloride (PVC) jẹ resini thermoplastic laini ti a ṣe nipasẹ polymerization ti monomer kiloraidi fainali.Nitori iyatọ ti awọn ohun elo aise, awọn ọna meji lo wa ti iṣelọpọ fainali kiloraidi monomer kalisiomu carbide ilana ati ilana epo.Sinopec PVC gba ilana idaduro meji, ni atele lati Japanese Shin-Etsu Chemical Company ati American Oxy Vinyls Company.Ọja naa ni resistance ipata kemikali to dara, ohun-ini idabobo itanna to dara julọ ati iduroṣinṣin kemikali to dara.Pẹlu akoonu chlorine giga, ohun elo naa ni idaduro ina ti o dara ati awọn ohun-ini piparẹ-ara.PVC jẹ rọrun lati ṣe ilana nipasẹ extrusion, abẹrẹ abẹrẹ, calendering, fifẹ mimu, fisinuirindigbindigbin, sisọ simẹnti ati imudani gbona, ati bẹbẹ lọ.
Ohun elo
PVC jẹ ọkan ninu awọn resini thermoplastic ti a lo julọ julọ.O le ṣee lo lati ṣe awọn ọja pẹlu lile lile ati agbara, gẹgẹbi awọn paipu ati awọn ohun elo, awọn ilẹkun profaili, awọn window ati awọn apoti apoti.
O tun le ṣe awọn ọja rirọ, gẹgẹbi awọn fiimu, awọn iwe, awọn okun ina mọnamọna ati awọn kebulu, awọn apoti ilẹ ati alawọ sintetiki, nipasẹ afikun awọn ṣiṣu ṣiṣu.
