Pali mitundu yambiri ya sera zomwe zili ndi zinthu zosiyanasiyana, koma katundu wawo ndi

mapulogalamu ali ndi zofanana zobadwa nazo.Monga mtundu wa zipangizo polima, tanthauzo la

"Sera" imatsindika kwambiri kufotokozera maonekedwe.Ambiri amakhulupirira kuti sera zochokera

Zogulitsa ziyenera kukhala ndi izi:

1. Kutentha kwachipinda ndi zinthu zolimba;

2. Kupitilira kusungunuka kwake, zinthuzo ziyenera kukhala ndi mamasukidwe otsika ndikukhala ngati a

madzi;

3. Wosasungunuka m'madzi.

Ena amawona kuti ma polima ena osungunuka m'madzi monga olimba a acrylic resin-based copolymers,

rosin, etc. ayeneranso kukhala wa mankhwala sera, koma kuganizira maganizo ochiritsira mu

mafakitale a zinthu zokutira zotengera madzi, ma polima osungunuka ndi madzi omwe amapezeka mu dongosolo mu a

Kusungunuka sikuphatikizidwa mu mankhwala a sera.

Kuyamba kwa main sera mndandanda mankhwala:

Zofunikira kwambiri zoyimilira zopangira ndi magwiridwe antchito ndi izi:

1.Sera ya Polyethylene: Imadziwikanso kuti polyethylene yotsika kwambiri yama cell, ambiri

Kulemera kwa molekyulu ya 1800 ~ 8000, kugawidwa mu polyethylene yapamwamba kwambiri komanso yotsika kwambiri

polyethylene, yokhala ndi thupi labwino komanso kukhazikika kwamankhwala, ndiyofunikira kwambiri

mtundu wa sera kupanga.

2.Polypropylene sera: Amadziwikanso kuti otsika molecular kulemera polypropylene, mkulu

crystallinity, kufewetsa mfundo, kuuma, ndi katundu wabwino thupi ndi kukhazikika kwa mankhwala.

Chifukwa ndi insoluble m'madzi, mankhwala sera sangathe ntchito mwachindunji madzi ofotokoza

ndondomeko, kotero iwo ayenera kukonzedwa prefabricated.

3.Sera ya parafini imapangidwa kuchokera ku mafuta oyenga.Nthawi zambiri amatchedwa olimba

parafini sera.Zigawo zake zazikulu ndi n-alkanes, malo osungunuka 52-72 °C, kachulukidwe 0.880-

0.915 g/cm3, kulowa (1/10 mm) : pafupifupi 15-20.

4. Sera ya Fischer-tropsch, yomwe imapangidwa ndi polymer ndi C0 ndi H2, imapangidwa ndi N-alkanes.

ndi pafupifupi opanda nthambi unyolo, choncho ali olimba kulimba, mkulu kusungunuka mfundo ndi mkulu

kuuma.Chifukwa cha kuchepa kwapang'onopang'ono kwa mafakitale a petrochemical m'tsogolomu, the

Chiyembekezo cha msika wa sera ya malasha ya fischer-tropsch chikuyembekezeka.

5.Sera ya Carnauba ndi mtundu wa ester wopangidwa ndi C20 ~ C30 wax acid ndi C24 ~ C30 sera.

mowa.Malo osungunuka ndi 81 ~ 86 °C ndipo kachulukidwe ndi 0.996 ~ 0.998.Kulowa kwa

pafupifupi 1, kuuma kwakukulu, kupaka gloss, zosavuta kupukuta, zosavuta kuziyika, zodula, "Mfumu ya

phula”mbiri.

Malingaliro a kampani Qingdao Sainuo Chemical Co.,Ltd.Ndife opangasera PE, PP sera, OPEwax, EVA
