Inye: Umbhobho wesinyithi otyhidiweyo uthintela ukusasazeka komlilo ngcono kakhulu kunombhobho weplastiki kuba umbhobho wesinyithi otyhidiweyo awutshi. Awuyi kuxhasa umlilo okanye utshise, ushiya umngxuma apho umsi kunye namalangatye anokungena khona kwisakhiwo. Kwelinye icala, umbhobho otshayo ofana nePVC kunye ne-ABS, unokutsha, Ukucima umlilo kwimbhobho otshayo kufuna umsebenzi omninzi, kwaye izixhobo zibiza kakhulu, kodwa ukucima umlilo kwimbhobho yesinyithi otyhidiweyo, umbhobho ongatshiyo, kulula ukuwufaka kwaye awubizi kakhulu.
Eyesibini：Enye yezona mpawu zibalaseleyo zombhobho wesinyithi kukuhlala ixesha elide kwawo. Ngenxa yokuba umbhobho weplastiki ufakwe ngobuninzi ukususela ekuqaleni kweminyaka yoo-1970, ubomi bawo bokusebenza abukakacaciswa. Nangona kunjalo, umbhobho wesinyithi usetyenziswe ukususela kwiminyaka yoo-1500 eYurophu. Enyanisweni, umbhobho wesinyithi ububonelela ngemithombo yaseVersailles eFransi kangangeminyaka engaphezu kwama-300.
Isithathu: Zombini ipayipi yesinyithi esitshisiweyo kunye nepayipi yeplastiki zinokuba sesichengeni sezinto ezibolayo. Ipayipi yesinyithi esitshisiweyo ichaphazeleka kukubola xa inqanaba le-pH ngaphakathi kwipayipi lehla liye ngaphantsi kwe-4.3 ixesha elide, kodwa akukho ndawo yokucoca amanzi eMelika evumela nantoni na ene-pH engaphantsi kwe-5 ukuba ilahlwe kwinkqubo yayo yokuqokelela amanzi amdaka. Yi-5% kuphela yomhlaba eMelika ebolayo xa ifakelwe kwisinyithi esitshisiweyo, kwaye xa ifakelwe kuloo mhlaba, ipayipi yesinyithi esitshisiweyo inokukhuselwa ngokulula nangokungabizi kakhulu. Kwelinye icala, ipayipi yeplastiki isengozini kwiiasidi ezininzi kunye nezinyibilikisi kwaye inokonakala ziimveliso zepetroliyam. Ukongeza, ulwelo olushushu olungaphezulu kwe-160 degrees lunokonakalisa iinkqubo zepayipi zePVC okanye ze-ABS, kodwa alubangeli ngxaki kwipayipi yesinyithi esitshisiweyo.
