Pakhoza kukhala abwenzi ena omwe samvetsetsa mawu oti polyethylene sera . Apa tikuwonetsa kaye kuti sera ya PE ndi chiyani. Sera ya PE ndi polyethylene yotsika kwambiri yama cell, yomwe imakhala yolemera pafupifupi 2000-5000, ndi osakaniza a hydrocarbon okhala ndi atomu ya kaboni pafupifupi 18-30. Zigawo zazikuluzikulu ndi alkanes liniya (pafupifupi 80% - 95%), ndi ochepa alkanes ndi nthambi payekha ndi monocyclic cycloalkanes ndi unyolo wautali mbali (chiwerengero cha onse awiri ndi zosakwana 20%). Kenaka, titatha kumvetsetsa sera ya PE, tidzabwereranso ku mutu waukulu ndikudziwitsani momwe tingasiyanitsire phula loona ndi lonyenga la PE.

1. Phula la phula la polyethylene
Nyama yeniyeni ya sera ya polyethylene yowombedwa imawoneka ngati pulasitiki. Zikuwoneka zolimba ndipo ndizofanana ndi chidutswa cha pulasitiki. Pamwamba ndi yosalala, translucent, zachilengedwe woyera kapena chikasu. Mukachiyang'ana, mudzawona kuti mulibe kusanjikiza mkati, mulibe ufa wa laimu, mawanga akuda ndi zonyansa zina, ndipo pali kuwala kwabwino mukamayang'ana ndi kuwala;
2. Gwirani ndi dzanja lanu
Sera yeniyeni ya polyethylene imakhala yosalala bwino. Zimamveka ngati pulasitiki osati sera. Ndilolimba, lophwanyika, losavuta kusweka, ndipo silimangirira pa kutentha kwabwino. Mabodza okhala ndi parafini, mafuta owumitsidwa ndi sera ya Fischer Tropsch ali ndimafuta. Amamva ngati mafuta ndipo amamva ngati makandulo, kapena amaoneka ngati ovuta komanso ofewa. Ngati ali mu mawonekedwe a ufa, apanga misa mukamawagwira ndi manja anu.

3. Kununkhira
Sera yeniyeni ya polyethylene imanunkhira ngati pulasitiki, pamene sera yabodza ya polyethylene imanunkha ngati sera kapena fungo lamphamvu;
4. Wiritsani m'madzi otentha
Ikani sera mu galasi ndikutenthetsa mpaka madzi awira kwa mphindi zisanu. Sera yeniyeni ya polyethylene ndi yomwe mawonekedwe ake amakhala osasinthika, ndipo sera ya polyethylene yomwe ili ndi zonyansa monga sera ya parafini ndi yomwe imakhala yomata kapena yopunduka. Ngakhale njira zoyesera ndizosiyana komanso malo oyesera ndi osiyana, malo ofewetsa a chinthu chenicheni ayenera kukhala apamwamba kuposa 100 ℃.
5. Gwiritsani ntchito mita yosungunuka, infrared spectrometer ndi kuyesa kwa nyukiliya maginito resonance
Malo osungunuka a sera ya polyethylene nthawi zambiri amakhala pafupifupi madigiri 105, ndipo kusungunuka kwake kumakhala kochepa. Zinthu zabodza zosakanizidwa ndi zinthu zina zimakhala ndi malo otsika osungunuka komanso osiyanasiyana osungunuka. Infrared spectrometer ili ngati diso lamoto. N’zosavuta kusiyanitsa zoona ndi zabodza, koma chidacho n’chokwera mtengo. Osatchulanso nyukiliya maginito resonance.
6. Kuona kwa sera ya polyethylene kunayesedwa poyezera mtundu wosungunuka, malo osungunuka, mtengo wa asidi ndi phulusa;

7. Yesani
Kuchuluka kwa sera yoyera ya PE ndi yaying'ono, katundu wogwetsa ndi wabwino, mankhwalawo sakhala ndi mpweya, komanso kuwala kwa chinthucho ndikwambiri, ndipo zinthu zosiyanasiyana za mankhwalawa zimasinthidwa. Sera yabodza ya PE ilibe zinthu zapamwambazi.
Njira zingapo zosavuta zodziwira sera yowona ndi yonama ya PE. Nthawi zambiri, ndi: kuyang'ana kumodzi, kukhudza kuwiri, kununkhiza katatu, zithupsa zinayi, mayeso asanu ndi kuyesa zisanu ndi chimodzi.
Malingaliro a kampani Qingdao Sainuo Chemical Co.,Ltd. Ndife opanga sera PE, PP sera, OPE sera, Eva sera, PEMA, EBS, Zinc / Calcium Stearate…. Zogulitsa zathu zadutsa REACH, ROHS, PAHS, FDA kuyesa.
Sainuo chidaliro sera, kulandira atafunsira anu!
