Eminye imiba malunga ne-polyethylene ekhlorini:

I-polyethylene ene-chlorine (CPE) yinto ye-polymer egcweleyo enembonakalo yomgubo omhlophe, ayinatyhefu kwaye ayinavumba. Inokumelana okuhle kwemozulu, ukumelana ne-ozone, ukumelana neekhemikhali, kunye nokumelana nokwaluphala, kunye nokumelana kakuhle neoyile, ukubambezeleka komlilo, kunye neempawu zombala. Ukuqina okuhle (kusaguquguquka kwi--30 ℃), ukuhambelana okuhle nezinye izinto ze-polymer, ubushushu obuphezulu bokubola, ukubola kuvelisa i-HCL, enokubangela ukusabela kwe-dechlorination ye-CPE.

Indlela yamanzi ye-polyethylene ekhlorini isetyenziswa kakhulu, eneendleko eziphantsi zemveliso kunye nongcoliseko olubi. Enye indlela yindlela yokumiswa, ekhulileyo. Ezasekhaya zinokuphuhliswa kwaye zisetyenziswe ngokukhawuleza, kwaye isantya sokomisa sikhawuleza. Isetyenziswa kakhulu kwiitanki zokugcina kunye nezakhiwo zentsimbi ukuphucula ukhuseleko lokwakha.

Iimodeli ze-polyethylene ekhlorini (CPE) zasekhaya ngokubanzi zichongwa ngamanani anjenge-135A, 140B, njl. Iinombolo zokuqala 1 kunye no-2 zimele i-crystallinity eseleyo (ixabiso le-TAC), u-1 umele ixabiso le-TAC phakathi kwe-0 kunye ne-10%, u-2 umele ixabiso le-TAC>10%, iinombolo zesibini nezesithathu zimele umxholo we-chlorine, umzekelo, u-35 umele umxholo we-chlorine we-35%, kwaye idijithi yokugqibela ngunobumba u-ABC, osetyenziselwa ukubonisa ubunzima be-molecular yezinto ezikrwada ze-PE. U-A ngoyena mkhulu kwaye u-C ngoyena mncinci.

Impembelelo yobunzima be-molecular: I-Chlorinated polyethylene (CPE) inobunzima obukhulu be-molecular kunye ne-viscosity ephezulu yokunyibilika kwizinto zayo zohlobo lwe-A. I-viscosity yayo ihambelana ne-PVC kakuhle kwaye inesiphumo esihle kakhulu sokusasazwa kwi-PVC, yenza inethiwekhi efanelekileyo efana ne-dispersion form. Ke ngoko, izinto zohlobo lwe-A ze-CPE zihlala zikhethwa njenge-modifier ye-PVC.

Isetyenziswa kakhulu kwi: ucingo kunye nentambo (iintambo zemigodi yamalahle, iingcingo ezichazwe kwimigangatho ye-UL kunye ne-VDE), ipayipi ye-hydraulic, ipayipi yesithuthi, iteyiphu, ipleyiti yerabha, ukuguqulwa kwepayipi yeprofayili yePVC, izixhobo zemagnethi, ukuguqulwa kwe-ABS, njalo njalo. Ingakumbi uphuhliso lweshishini leentambo kunye necandelo lokuvelisa iimoto luye lwabangela imfuno yokusetyenziswa kwe-CPE esekelwe kwirabha. I-CPE esekelwe kwirabha yirabha ekhethekileyo yokwenziwa enentsebenzo egqwesileyo, ukumelana nobushushu kwi-oksijini kunye nokuguga kwe-ozone, kunye nokungalali kakuhle komlilo.

Izinto ezichaphazela ubushushu bokubola kwe-CPE

Iimpawu zeCPE ngokwayo zinxulumene nomxholo wayo we-chlorine. Ukuba umxholo we-chlorine uphezulu, kulula ukubola;

Inxulumene nobunyulu. Ukususwa ngokwaneleyo kwee-initiators, ii-catalysts, ii-asidi, iziseko, njl. ezongeziweyo ngexesha lenkqubo ye-polymerization, okanye ukufunxwa kwamanzi ngexesha lokugcina nokuthuthwa, kunokunciphisa uzinzo lwe-polymer. Ezi zinto zinokubangela ukusabela kokonakala kwee-ion ze-molecular, kwaye i-CPE iqulethe izinto ezinobunzima obuphantsi bee-molecular ezifana ne-Cl2 kunye ne-HCl, ezinokukhawulezisa ukubola kobushushu be-resin;
