Nyika yoonse - Polyethylene Mupati: Polymer iibelesyegwa munzila zyiingi
Zibeela Zipati Zyakubelesya
Polyethylene ilizibinkene akaambo kakukazya misamu iikola. Ulakonzya kukazyigwa kapati amakemikalu aasiyene-siyene, kubikkilizya ama asidi, ma base, alimwi ama solvents. Eechi chintu chipa kuti ube chintu chibotu kubelesegwa mumakwebo aamisamu, ooko nkochibelesyegwa kupanga zibelesyo zyakuyobweda zintu, mapaipi, azintu zikonzya kubamba kabotu zintu zikonzya kubola. Kubula nguzu kwawo kwamakemikalu akwalo kulasinizya kuti tasofwaazyi zintu zili mukati, akubamba kusalala akusyomeka kwazintu zyakabambwa.
Mumakwebo aakupaka, polyethylene ili koonse koonse. Bunji bwayo busyoonto akukonzya kuchincha zipa kuti ibe kabotu mukupanga mafilimu, zibbeeke, aziyobwedo zitakatazyi alimwi ziyumu. Chipa chikwabilizyo chibotu kuzwa kukuteta, muuya, azimwi zintu zili muchilengwaleza, ikukwabilila zintu zibikkidwe mumabbokesi kuti zitanyonyooki akubola. Kufumbwa naa nkupaka zyakulya, ooko nkokugwasya kubamba bupya abubotu bwazintu zikonzya kubola, naa nkupaka zintu zyakubelesya, ooko nkokupa nzila mbotu yakupaka, polyethylene ilaa mulimo mupati mukukwabilila akusambalwa kwazintu.
Mulimo wakuyaka awalo ulagwasyigwa kapati a polyethylene. Chibelesegwa mukupanga mapaipi aakubelesya kugwisya maanzi amuwo. Mapaipi aa polyethylene alizyibidwe akaambo kakuyuma kwawo, kuyuma, alimwi akukazya kutyompokelwa akutyompokelwa. Zilaa buumi bulamfwu bwakubeleka mpawo taziyandiki kubambululwa pe, zipa kuti zibelesyegwe kabotu mumapulojekiti aakuyaka. Kuyungizya waawo, polyethylene ilabelesyegwa muzintu zyakukwabilila, kupa bube bwakukwabilila kupya kapati ibugwasya kucesya kubelesya manguzu mumaanda.
Mumakwebo aakupanga myootokala, polyethylene ilabelesyegwa mumilimo yiindene. Chibelesyegwa kupanga zintu zyamukati zilimbuli madashiboodi, milyango, azivwunisyo zyazyuuno nkaambo nchintu chiubauba, nchuubauba kubumba mpawo chilibonya kabotu. Alimwi ilabelesyegwa muzibeela zyaanze mbuli mabbampa ama fender, ooko kukwabililwa kwayo kugwasya kusumpula lukwabililo akuyuma kwamootokala. Kwiindawo, polyethylene ilabelesyegwa mumatanki aamafuta amumisela yamafuta, nkaambo kakuti taikonzyi kunjila mumafuta alimwi akukkalilila kwamakemikalu.

Mubufwaafwi
Polyethylene yesu ya Global - Premier ilajanwa mumisela yiindene-indene kutegwa izuzikizye ziyandikana mumakkampani aasiyene-siyene. Nikuba kuti n polyethylene iijisi nguzu kapati (HDPE) iibelesyegwa muzintu ziyandika nguzu zipati akuyuma, naa i polyethylene iijisi nguzu ziniini (LDPE) iibelesyegwa muzintu zikonzya kunyamuka akutandabala, tulapa zintu zyiingi. Kabunga kamwi akamwi kalasunkwa kabotu-kabotu kuchitila kuti kakuli kabotu, kubikkilizya akusunkwa kwabulemu, mweelwe wakunyenguluka, kusima kwanguzu, akulampa. Ipolyethylene yesu ilabikwa muzibelesyo zyeelede zyakukwabilila kuti ikwabililwe muchiindi chakuyobolwa akutolwa. Nikuba uli kkampani iibamba zintu muEzhiya, kkampani yakuyaka muYulopu, kkampani iipanga myootokala muNorth America, naakuti kkampani iipanga misamu muSouth America, Global - Premier Polyethylene yesu ninzila iisyomeka alimwi iibeleka obotu loko njoyelede kuchita kuti zintu zyako zibeleke kabotu.
