Nyika Yoonse - Mupati PVA: Polymer iili kabotu kapati iibelesyegwa mumilimo yiindene-indene
Zibeela Zipati Zyakubelesya
PVA ilabelesyegwa kapati mumakwebo aazisani. Chibeleka mbuli chintu chakupima bupati bwantambo, ikusumpula nguzu zyazyo akuteteeta kwazyo muchiindi chakuluka. Eezi zigwasya kuchesya kutyoka akusumpula bubotu bwachisani. Musule lyakuluka, PVA ilakonzya kugwisigwa chakufwambaana kwiinda mukusanzya, akusiya chisani mbuli mbocakabede kumatalikilo. Mukuyungizya, PVA ilabelesyegwa mukupanga zintu zyakuvwumba zyakusama azintu zyakunamatizya, kupa kuti kakuli kabotu akuzumanana.
Mumakwebo aamapepa, PVA ibelesyegwa mbuli chintu chakupima bupati bwamapepa antoomwe akujatisya. Mbuli chintu chakupima bupati bwaatala, chisumpula kukazyigwa kwamaanzi, kusima, akusimbwa kwamapepa. Ipanga filimu iteteete, iisalala aapepa, ikulesyela ingi kuti itamwaiki mpawo isumpula kusalala kwazifwanikiso zilembedwe. Mbuli chintu chakujata, PVA ilabelesyegwa mukupanga mapepa aamapepa, ikusumpula kujatana aakati kachivwumbyo abwaanda, akusumpula nguzu akuyuma kwamapepa.
PVA alimwi nchintu chiyandikana loko mumulimo wakunamatika. Chili aanguzu zyakunamatika zibotu, ikapati kuzintu zijisi mapopwe mbuli nkuni, mapepa, azisani. Zinamatika zipangidwe a PVA zilakonzya kunywika mumaanzi, nzyuba kubelesya, alimwi zilaanguzu zyakujata kabotu. Zilabelesegwa kapati mumakkampani aakuyaka, aakupanga zintu zyamuŋanda, alimwi akupakila zintu zisiyene-siyene. Mukuyungizya, zintu zyakunamatika zya PVA zilakonzya kuchinchululwa azintu zimwi kuti zitanjili mumulilo, zitanjili mumaanzi, azintu zimwi kutegwa zizuzikizye ziyandikana zyakubelesya.
Mumulimo wakuvwumba, PVA ibelesyegwa mbuli chintu chipanga mafilimu. Ipanga filimu iisalala, iikonzya kuzungaana, alimwi iitanjilili maanzi atala aachintu chibikkidwe, ichikwabilila kuzwa kukutontola, makemikalu, akumimuni ya UV. Zivwumbyo zye PVA zilabelesyegwa kapati mukukwabilila zisamu, nsimbi, antoomwe amapulasitiki. Alakonzya kubelesegwa mbuli ntalisyo naakuti mbuli chivwumbyo chaakati-akati kuchitila kuti chivwumbyo chijatane akubeleka kabotu.

Mubufwaafwi
PVA yesu ya Global - Premier ilajanwa mumisela yiindene, kubikkilizya amapopwe, ma granules, alimwi ama solution, kuti izuzikizye ziyandikana zyamakkampani aasiyene. Igiredi imwi aimwi ya PVA ilijisi bube bulibedelede mbuli kuyuma, mweelwe wa polymerization, amweelwe wa alcoholysis, zikonzya kuchinchululwa kweendelanya aziyandwa abasikuula. Zintu zyesu zya PVA zilabikkwa mumabbokesi aatakwe maanzi alimwi aatanjili muya kuchitila kuti kazili kabotu akukkalilila muchiindi chakuyobolwa akutolwa. Nikuba uli sikupanga zizwaato muEzhiya, sikupanga mapepa muYulopu, sikupanga zintu zyakunamatika muNorth America, naakuti inkamu iibamba zyakusama muSouth America, Global - Premier PVA yesu ninzila iisyomeka alimwi iili kabotu iikonzya kukugwasya kusumpula bubotu bwazintu zyako.
