I-propylene oxide(PO) sisixhobo esiluhlaza esibalulekileyo ekuvelisweni kweecomicals ezahlukeneyo. Uluhlu lwayo lwezicelo lubandakanya ukuveliswa kwe-polyurethane, polyeether, kunye nezinye iimpahla ezisekwe kwiPolymer. Ngemfuno ekhulayo yeemveliso ezisekwe kwimveliso yamashishini anjengokwakhiwa, izithuthi, ukupakisha, kunye nefanitshala, imarike ye-PO kulindeleke ukuba ifumane ukukhula okukhulu kwiminyaka ezayo.

Abaqhubi bokukhula kwentengiso

Ibango le-PO liqhutywa ikakhulu ngamashishini okuphumelela kunye neemoto. Icandelo lokwakha ngokukhawuleza, ngakumbi kuqoqosho oluhlumayo, likhokelele kwimfuno yemfuno yokusebenza kakhulu kunye nezinto ezinokufunyanwa ngempumelelo. I-Polypurethane esekwe kwi-Polyurethane isetyenziswa ngokubanzi kumzi-mveliso wokwakha ukuze abolekwe i-insultives yabo ibalaseleyo kunye neepropathi zomlilo ongazithandiyo.

Ngapha koko, ishishini le-AutoMotive libe ngumqhubi obalulekileyo wentengiso ye-TOO. Ukuveliswa kwezithuthi kufuna i-upethora yezinto ezinokumelana namaqondo obushushu aphezulu kunye noxinzelelo lomatshini. I-Polymers esekwe kwi-POLLYS ihlangabezana nezi mfuno kwaye isetyenziswa ngokubanzi kwimveliso yezinto ezizenzekelayo.

Imiceli mngeni yokukhula kwentengiso

Ngaphandle kwamathuba amaninzi okukhula, imakethi ye-PO ijongene nemiceli mngeni. Omnye wemiceli mngeni ephambili kukuzinza kwamaxabiso ezinto ezinqabileyo. Amaxabiso ezinto eziluhlaza ezifana ne-proplenene neoksijini, ebaluleke kakhulu kwimveliso ye-PO, iphantsi kozuko olubalulekileyo, olukhokelela ekungazinzini kwiindleko zemveliso. Oku kunokuchaphazela inzuzo yabavelisi base-PO kwaye kunokuba nefuthe kubuchule babo bokufezekisa imfuno ekhulayo.

Omnye umngeni yiMigaqo yeNdawo engqongqo ebekelwe ishishini lekhemikhali. Ukuveliswa kwe-PO Veza inkunkuma eyingozi kunye nemveliso yegesi yeGreenhouse, ekhokelele ekunyukeni kweliso kunye nezohlwayo zabasemagunyeni. Ukuthobela le migaqo, abavelisi base-PO kufuneka balondoloze kunyango lwenkunkuma ebiza inkcitho kunye nokunyusa iindleko zabo zemveliso.

Amathuba okukhula kwentengiso

Ngaphandle kwemiceli mngeni, kukho amathuba aliqela okukhula kwentengiso ye-TOO. Elinye lakwalelani imfuno yokukhulisa izinto zokufakwa kwishishini lokwakha. Njengoko icandelo lokwakha liyanda kuqoqosho oluhlumayo, imfuno yezixhobo zokuncedisa ekulindelwe ukuba inyuke. I-Polypurethane esekwe Polyurthane ibonelela ngeepropathi ezizodwa ezibenza balungele uluhlu olubanzi lwezicelo zokuncedisa.

Elinye ithuba lilele kumzi mveliso ngokukhawuleza. Ukugxila okwandayo kwisithuthi esikhanyayo kunye nokusebenza kwe-oyile, kukho isidingo esikhulayo sezinto ezinokukhanya ezinokukhusela ubushushu obuphakamileyo kunye noxinzelelo lomatshini. I-Polymers esekwe kwi-POLLYS ihlangabezana nezi mfuno kwaye inokuba inokuthi ithathe indawo yezilwanyana ezifana neglasi kunye nentsimbi kwimveliso yezithuthi.

Ukuqukumbela

Imbonakalo yentengiso ye-propylene oxide inesidima, iqhutywa ngamashishini okuphumelela kunye neemoto. Nangona kunjalo, ukuzibhokoxa kumaxabiso aphantsi komhlaba kunye nemigaqo engqongqo yendalo esingqongileyo kunyanzeliswa ukukhula kwentengiso. Ukuzibandakanya kumathuba, abavelisi base-PO kufuneka bahlale bengama-Arestment uthatha indawo yentengiso, utyalomali kuphando kunye nophuhliso, kwaye wamkele ukuvelisa okuzinzileyo kunye nokusingqongileyo.
