Popanga mbiri, mafuta omwe amagwiritsidwa ntchito ndi osiyana chifukwa cha machitidwe osiyanasiyana okhazikika.Mu dongosolo lokhazikika la mchere wotsogolera, stearic acid, glyceryl stearate ndi polyethylene sera akhoza kusankhidwa ngati mafuta;mu dongosolo lokhazikika la calcium zinc composite stabilization system ndi osowa padziko lapansi composite stabilization system, stearic acid, butyl stearate, parafini, pa wax ndi calcium stearate akhoza kusankhidwa ngati mafuta;mu organic tini formula, calcium stearate, parafini, wothiridwa ndi polyethylene sera akhoza kusankhidwa ngati mafuta.Zofunika kwambiri zamafuta wamba ndi awa:

(1) Calcium stearate
ufa woyera, kusungunuka 148-155 ℃, sanali poizoni, lubricity kwambiri ndi processability, palibe kuipitsa sulfide, ntchito pamodzi ndi zofunika mchere mchere ndi sopo wotsogolera, akhoza kusintha gel osakaniza liwiro, ndi mlingo zambiri 0.1-0.4PHR.
(2) Sera ya polyethylene
White ufa, kufewetsa mfundo ndi za 100-117 ℃.Chifukwa cha kulemera kwake kwa maselo, malo osungunuka kwambiri komanso kusinthasintha kochepa, zimasonyezanso zowoneka bwino za mafuta pa kutentha kwakukulu ndi kumeta ubweya.Ndi oyenera okhwima PVC single ndi amapasa wononga extrusion, ndi kuchuluka wamba 0.1-0.5PHR.
(3) Sera ya polyethylene oxidized
White kapena chikasu ufa kapena tinthu, oxidized polyethylene sera akadali zosemphana ndi PVC, ngakhale lili pang'ono magulu polar, koma kondomu Mwachangu ndi mkulu, amene akhoza kusintha kondomu pakati polima ndi zitsulo, kusintha extrusion Mwachangu, kusintha kubalalitsidwa kwa colorants, ndikupatsa zinthu zowonekera bwino komanso zowala.Mlingo wa 0.1-0.5PHR.

(4) Stearic acid
Tinthu tating'onoting'ono toyera kapena tachikasu, tosungunuka 70-71 ℃.Imasinthasintha pang'onopang'ono pa 90-100 ℃.Amagwiritsidwa ntchito ngati lubricant kunja pokonza PVC yolimba.Kuchuluka kwake kumakhala 0.2-0.5PHR, ndipo kumakhala ndi zotsatira zolepheretsa kukula kwa chromatography, koma ndikosavuta kupopera chisanu ngati kuchuluka kwake kuli kwakukulu.

(5) Serafini
Malo osungunuka 57-63 ℃, opanda magulu a polar, ndi mafuta akunja.Chifukwa cha kutsika kwake kosungunuka, kutuluka kwa nthunzi kosavuta, ndi kutsika kwa kusungunuka kwa viscosity, imatha kugwira ntchito yopaka mafuta pamtunda wopapatiza.Ndi yoyenera kutulutsa ndi single and twin screw extruders, ndi mlingo wamba wa 0.1-0.8PHR.Izi sizimawonekera bwino ndipo ndizosavuta kutembenukira zoyera.
M'zochita, zimapezeka kuti mafuta awiri kapena kuposerapo akagwiritsidwa ntchito palimodzi, amakhala ndi zotsatira zosiyana ndi pamene akugwiritsidwa ntchito okha.Popanga zida za mbiri, zambiri zimasakanizidwa.Dongosolo lofananira ndi mawonekedwe amafuta wamba amafotokozedwa mwachidule motere:
(1) Calcium stearate - Paraffin (polyethylene wax) mafuta dongosolo
Kugwiritsiridwa ntchito kwa calcium stearate kokha mu chilinganizo kumatha kufulumizitsa pulasitiki, kupititsa patsogolo kusungunuka kwa viscosity, kuonjezera torque, ndikukhala ndi zotsatira zina zowononga.Kugwiritsa ntchito parafini kokha kumawonetsa kuchedwa kwa pulasitiki, torque yocheperako, ndipo palibe kuwononga.Pamene sera ya calcium stearate ndi parafini (polyethylene sera) ikasakanizidwa mu gawo linalake, zimasonyeza zotsatira zabwino, ndipo mtengo wa torque wa zinthuzo ukhoza kuchepetsedwa kwambiri.Ichi ndi chifukwa parafini likulowerera mu kashiamu stearate mamolekyu, kulimbikitsa kondomu, kusonyeza amphamvu synergistic zotsatira, ndi bwino kubalalitsidwa kwa lubricant.

(2) Stearic acid – Parafini (polyethylene sera) mafuta dongosolo
Limagwirira ndi chimodzimodzi ndi kashiamu stearate - Paraffin (polyethylene sera) dongosolo, amene angathe kusintha bata matenthedwe chilinganizo, kuchepetsa shrinkage, kusintha fluidity, ndi atsogolere demoulding.
(3) Sera ya oxidized polyethylene - esters - calcium stearate
Pamene sera ya polyethylene, ester ndi calcium stearate zimagwiritsidwa ntchito palimodzi, nthawi yopangira pulasitiki mwachiwonekere imatalika ndi kuchuluka kwa sera ya polyethylene, pamene sera ya polyethylene ya oxidized, sera ya parafini, ester ndi calcium stearate imagwiritsidwa ntchito palimodzi, nthawi ya plasticizing imachulukitsidwa poyamba. ndiye utachepa ndi kuchuluka kwa oxidized polyethylene sera kuchuluka, kusonyeza zoonekeratu synergistic kwenikweni.
Pomaliza, powerenga chilinganizo cha mbiri ya PVC, ndikofunikira kumvetsetsa osati mawonekedwe ndi ntchito zamafuta aliwonse, komanso mphamvu ya synergistic pakati pawo.Kuphatikiza apo, fomula ya mbiri ya PVC iyenera kusinthidwa ndikusinthidwa malinga ndi kusiyana kwa zida zopangira ndi nkhungu.
