Eyokuqala: Umbhobho wentsimbi wokuphoswa unqanda ukusasazeka komlilo ngcono kunombhobho weplastiki kuba intsimbi ayitshi. Ayisayi kuwuxhasa umlilo okanye itshise, ishiya umngxuma apho umsi namadangatye anokungena khona kwisakhiwo. Kwelinye icala, umbhobho otshayo onje nge-PVC kunye ne-ABS, unokutsha uphele, Ukucima umlilo kumbhobho otshayo kunzima kakhulu, kwaye izixhobo zibiza imali eninzi, kodwa ukumisa umlilo kumbhobho wentsimbi, umbhobho ongatshiyo, kulula ukuwufakela kwaye akubizi mali ininzi.
Ezimbini:Olunye lweempawu ezinomtsalane zombhobho wentsimbi kubomi obude. Ngenxa yokuba ipayipi yeplastiki ifakwe ngobuninzi kuphela ukususela ekuqaleni kwe-1970, ubomi bayo benkonzo ayikacaciswa. Nangona kunjalo, umbhobho wentsimbi usetyenziswe ukususela ngo-1500 eYurophu. Ngokwenyani, umbhobho wentsimbi ububonelela ngemithombo yaseVersailles eFransi iminyaka engaphezu kwama-300.
Ezintathu: Zombini umbhobho wentsimbi kunye nombhobho weplastiki unokuba sesichengeni kwizinto ezidlayo. Umbhobho we-iron owenziweyo uphantsi kokuhlwa xa inqanaba le-pH ngaphakathi kombhobho lihla liye ngaphantsi kwe-4.3 ixesha elide elide, kodwa akukho sithili sombhobho welindle eMelika ovumela nantoni na ene-pH engaphantsi kwe-5 ukuba ilahlwe kwinkqubo yayo yokuqokelela ugutyulo. Kuphela yi-5% yemihlaba yaseMelika edla isinyithi, kwaye xa ifakwe kuloo mihlaba, umbhobho wentsimbi unokukhuselwa lula kwaye ungabizi. Kwelinye icala, umbhobho weplastiki usesichengeni kwiiasidi ezininzi kunye nezinyibilikisi kwaye ungonakaliswa ziimveliso zepetroleum. Ukongeza, ulwelo olushushu ngaphezu kwe-160 degrees lungonakalisa iinkqubo zemibhobho ye-PVC okanye ye-ABS, kodwa akukho ngxaki kumbhobho wentsimbi.
