Yintoni isilwanyana sasekhaya? Uhlalutyo olubanzi lwe-Polythylene Terephthalatelate
I-PET, okanye i-Polythylene Terephthalate, yinto ye-polymer esetyenziswe ngokubanzi kwishishini lekhemikhali. Kweli nqaku, siza kubonelela ngohlalutyo olunzulu lwenkcazo yezilwanyana zasekhaya, iindawo zalo zesicelo, inkqubo yemveliso kunye nezibonelelo zayo, ukuze zibonelele abafundi ngesilwanyana esibaluleke kakhulu.
Inkcazo kunye neepropathi ezisisiseko zesilwanyana sasekhaya
Yintoni isilwanyana sasekhaya? Ngokucacileyo, isilwanyana sisiporho se-thermoplastic eyenziwe yi-Polymisation ye-Perephthayic Acid nase-Ethylene Glycol.Isakhiwo sekhemikhali sinika iipropathi zasekhaya ezifana namandla aphezulu, ukumelana nobushushu kunye nokungafihli ubushushu kunye nokungafihli ubushushu kunye nokungafihli ubushushu. Ezi ndawo zenza ukuba zithanda izinto ezikhethayo kwiimeko ezininzi zesicelo, ngakumbi kwicandelo lokupakisha.
Iindawo eziphambili zesicelo sesilwanyana sasekhaya
Isilwanyana sasekhaya sisetyenziswa kuluhlu olubanzi lwezicelo, kugxilwe kwiindawo ezimbini eziphambili: Izinto zokupakisha izinto kunye nemveliso yefibre. Kumzi-mveliso wepakethi, isilwanyana sasekhaya sisetyenziswa ngokukodwa ekwenzeni iibhotile zeplastiki, izikhongozeli zokutya kunye nemveliso engaphandle kwephakheji, ngakumbi ekuvelisweni kweentsinga zePolyester. Impahla eyenziwe ngeentsinga zePolyerter kukunxiba nzima, kulula ukuhlamba kwaye ukhawuleze ukome, kuyenze ilungele ukunxiba yonke imihla.
Inkqubo yemveliso yezilwanyana
Ukuqonda ukuba i-Pet ifuna ukuba i-in-in-in-in-in-in-vere kwinkqubo yayo yemveliso, eyenziwa ngeendlela ezimbini eziphambili: inyathelo elinye (inyathelo ngqo) kunye nenqanaba elinamanyathelo amabini (enterter). Kwinkqubo yenyathelo elinye, i-Terephthayic Acid iphendulwa ngokuthe ngqo i-ithylene Glycols kwiqondo lobushushu, ngelixa i-polycodes esetyenzisiweyo, kwaye i-polycovieds esetyenzisiweyo isebenza, i-polycoving ye-Engling, ukubetha, ukubetha, okanye Inaliti-ubunjiweyo, ukwenzela ukulungiselela imveliso ebunjiweyo.
Izibonelelo kunye nokuzinza kwesilwanyana sasekhaya
Yintoni isilwanyana sasekhaya? Ukusuka kwindawo yokugcina iminikelo, izibonelelo zokuxoka kwesilwanyana ekuphindeni kwakhona; Iimveliso ze-PET zinokuphinda zisetyenziselwe ukuphinda zisebenze kwi-pyrolysis, ukuphinda kusetyenziswe kwakhona iikhemikhali kunye nezinye iindlela zokunciphisa ukungcoliseka kwezendalo, kunye namandla asekhaya kunye neepropathi ezikhanyayo kunye neendleko zothutho. Ezi mpawu zenza izilwanyana zasekhaya enye yezona zinto ziluncedo zingenantsingiselo kwishishini lanamhlanje.
Ukuqukumbela
Ukushwankathela, yintoni isilwanyana sasekhaya? Yinto esebenzayo kakhulu polymer ngoluhlu olubanzi lwezicelo.edlala indima ebalulekileyo kwishishini lanamhlanje ngenxa yeepropathi zalo ezibalaseleyo, uluhlu olubanzi lwezinto kunye nokuphinda usebenzise kwakhona. Nokuba kusekwe izinto zokupakisha kubomi bemihla ngemihla okanye imveliso yefibre kwishishini lendwangu, impembelelo yezilwanyana zasekhaya kuyo yonke indawo. Ke ngoko, ukuqondwa okunzulu kwento leyo ibalulekileyo ekuqondeni iimeko zezixhobo zekhemikhali zale michiza.
