(3) Oxidized polyethylene kakin zuma
White ko yellowish foda ko barbashi, oxidized polyethylene kakin zuma ne har yanzu m tare da PVC, ko da yake shi ya ƙunshi wani karamin adadin iyakacin duniya kungiyoyin, amma lubrication yadda ya dace ne high, wanda zai iya inganta lubrication tsakanin polymer da karfe, inganta extrusion yadda ya dace, inganta extrusion yadda ya kamata. tarwatsa masu launi, kuma suna ba da samfurori masu kyau nuna gaskiya da haske.Matsakaicin 0.1-0.5PHR.

(4) stearic acid
Barbashi fari ko rawaya, madaidaicin narkewa 70-71 ℃.Yana volatilizes a hankali a 90-100 ℃.Ana amfani dashi azaman mai mai na waje a cikin sarrafa PVC mai wuya.Adadin shine gabaɗaya 0.2-0.5PHR, kuma yana da tasirin hana ƙwanƙwasa chromatography, amma yana da sauƙin fesa sanyi idan adadin ya yi yawa.

(5) Paraffin kakin zuma
Matsayin narkewa 57-63 ℃, ba tare da ƙungiyoyin polar ba, man shafawa ne na yau da kullun na waje.Saboda ƙarancin narkewar wurinsa, ƙanƙara mai sauƙi, da ƙarancin narkewa, zai iya taka rawar mai kawai a cikin kunkuntar kewayo.Ya dace da extrusion ta guda ɗaya da tagwayen dunƙule extruders, tare da babban sashi na 0.1-0.8PHR.Wannan samfurin yana da rashin daidaituwa kuma yana da sauƙin juya fari.
A aikace, an gano cewa idan aka yi amfani da man shafawa biyu ko fiye tare, suna da tasiri daban-daban fiye da lokacin da aka yi amfani da su kadai.A cikin tsari na kayan bayanin martaba, yawancin su suna haɗuwa.An taƙaita tsarin daidaitawa da halayen man shafawa na gama gari kamar haka:
(1) Calcium stearate - Paraffin (polyethylene wax) tsarin lubrication
Yin amfani da alli stearate kadai a cikin dabara zai iya hanzarta da plasticization, inganta narke danko, ƙara da karfin juyi, da kuma samun wani demoulding sakamako.Amfani da paraffin kadai yana nuna jinkirin yin robobi, raguwar juzu'i, kuma ba shi da wani tasiri.Lokacin da calcium stearate da paraffin wax (polyethylene wax) suna haɗuwa a cikin wani nau'i na musamman, yana nuna sakamako mai kyau, kuma za'a iya rage yawan ƙimar kayan aiki da yawa.Wannan shi ne saboda paraffin yana shiga cikin kwayoyin stearate na calcium, yana ƙarfafa lubricating, yana nuna tasiri mai ƙarfi na synergistic, da inganta tarwatsawar mai.

(2) Stearic acid - Paraffin (polyethylene wax) tsarin lubricating
Tsarin daidai yake da na calcium stearate - Paraffin (polyethylene wax) tsarin, wanda zai iya inganta kwanciyar hankali na thermal na dabara, rage shrinkage, inganta ruwa, da sauƙaƙe demoulding.
(3) Oxidized polyethylene kakin zuma - esters - calcium stearate
Lokacin da aka yi amfani da polyethylene da kakin zuma, ester da calcium stearate tare, lokacin filastik yana tsawanta a fili tare da karuwar adadin polyethylene da kakin zuma, yayin da ake amfani da kakin polyethylene oxidized, paraffin wax, ester da calcium stearate tare, lokacin yin filastik yana ƙaruwa da farko. sannan ya ragu tare da karuwar adadin polyethylene oxidized, yana nuna tasirin haɗin gwiwa a bayyane.
A ƙarshe, lokacin nazarin ma'auni na bayanin martaba na PVC, dole ne a fahimci ba kawai halaye da ayyuka na kowane mai mai ba, har ma da tasirin synergistic tsakanin su.Bugu da ƙari, tsarin bayanin martaba na PVC yana buƙatar daidaitawa da canza shi bisa ga bambance-bambancen kayan aiki da kayan aiki.
