Ukukhetha ipayipi A okanye ipayipi B yingxaki eqhelekileyo xa abantu bethenga Imibhobho ye-PVC, kodwa bambalwa abantu abanokubona ngokucacileyo umahluko ocacileyo phakathi kwazo.
Oku kulandelayo sisishwankathelo somahluko amane onokuwasebenzisa:
1. Imigangatho eyahlukeneyo
Umbhobho A: Umbhobho A wamkela umgangatho wesizwe we-GB/T 5836.1-2018 (umgangatho wephayiphi ye-polyvinyl chloride (PVC-U) engqongqo yokwakha amanzi), eyiphayiphi esemgangathweni wesizwe;
Umbhobho B: Umbhobho B wamkela umgangatho weshishini kwaye ngumbhobho osemgangathweni weshishini;
2. Ubukhulu obahlukeneyo
Umbhobho A: Ubukhulu bodonga lombhobho A bukhulu, njengokuba ubukhulu bodonga lombhobho ongama-50mm yi-2.0mm, ubukhulu bodonga lombhobho ongama-75mm yi-2.3mm, ubukhulu bodonga lombhobho ongama-110mm yi-3.2mm, ubukhulu bodonga lombhobho ongama-160mm yi-4.0mm, ubukhulu bodonga lombhobho ongama-200mm yi-4.9mm, njl.njl.
Umbhobho B: Ubukhulu bodonga lombhobho B buncinci, njengokuba ubukhulu bodonga lombhobho we-50mm yi-1.8mm, ubukhulu bodonga lombhobho we-75mm yi-2.0mm, ubukhulu bodonga lombhobho we-110mm yi-2.8mm, kwaye ubukhulu bodonga lombhobho we-160mm yi-3.0mm.
3. Ixabiso elahlukileyo
Umbhobho A: Umbhobho A unezixhobo ezingcono, ubukhulu bodonga obungaphezulu, amandla aphezulu, kunye nexabiso eliphezulu;
Umbhobho B: Umbhobho B unesixa esiphezulu se-calcium powder, ubukhulu bodonga bukhulu kancinci, unamandla amabi kancinci, kwaye unexabiso eliphantsi;
4. Iindlela ezahlukeneyo zokusetyenziswa
Umbhobho A: Umbhobho A udla ngokusetyenziselwa ubunjineli bokukhupha amanzi kunye nokukhupha umoya ngeemfuno eziphezulu, kwaye awusetyenziswa rhoqo emakhaya.
Umbhobho B: Umbhobho B ikakhulu wenzelwe ubunjineli bokuhambisa amanzi, ukukhupha umoya kunye nokusetyenziswa ekhaya ngeemfuno eziphantsi kakhulu;
Umahluko phakathi Umbhobho wePVC A kunye nombhobho B zigxile kakhulu kwiingongoma ezine ezingentla. Ndiyathemba ukuba ziya kukunceda.
Eneminyaka ephantse ibe ngama-20 kwishishini lezixhobo zokukhupha izixhobo ezikrelekrele, ubambe iindima eziphambili kwiJwell Machinery, kuquka uMphathi Jikelele kunye noSihlalo ojikelezayo. Ukusukela ngo-2024, ulawule iinkampani ezininzi ezincedisayo, eqhuba ukwandiswa kweshishini kunye nokuphuculwa kwemizi-mveliso, ngelixa ekhokela ubuchule kwimveliso ekrelekrele kunye nokukhula kwehlabathi.
