Tetrahydroforunaniyingxenye yamakhemikhali ngefomula ye-molecular c4h8o. Uketshezi olungenamibala, oluvuthayo ngephunga elimnandi elimnandi. Lo mkhiqizo uyi-solvent ejwayelekile emikhakheni ehlukahlukene, kufaka phakathi amakhambi, amapulasitiki kanye nokukhiqizwa kwe-polymer. Ngenkathi inezingozi ezithile ezingaba khona, zizonke, i-tetrahydroforunan akuyona umkhiqizo oyingozi.
Ingozi eyodwa engaba khonaTetrahydroforunanukuthambisa kwayo. Uketshezi une-flashpoint ka -14 ° C futhi angakwazi ukusula kalula uma kuhlangana ne-spark, ilangabi noma ukushisa. Kodwa-ke, le ngozi ingalawulwa ngokulandela izinqubo zokugcina eziphephile nezinqubo zokuphatha. Ukunciphisa ubungozi bomlilo nokuqhuma, kubalulekile ukugcina umkhiqizo ungasuki emithonjeni yokulahla futhi usebenzise umoya omncane.
Enye ingozi engaba khonaTetrahydroforunanIkhono layo lokudala ukucasuka kwesikhumba kanye nokushiswa kwamakhemikhali. Lapho uketshezi luqala ukuxhumana ngqo nesikhumba, kungadala ukucasuka, ubomvu nokuvuvukala. Le ngcuphe ingancishiswa ngokugqoka izingubo ezifanele kanye nemishini yokuvikela ngenkathi iphatha umkhiqizo. Amagilavu, ama-goggles, nezingubo zokuvikela kungavimbela ukuvezwa kwesikhumba.
TetrahydroforunanFuthi kuwuketshezi olushintshashintshayo, okusho ukuthi kungashintsha kalula futhi kuveze ingozi yokuphefumula. Ukuchayeka isikhathi eside kuma-Vapors kungaholela ekubeni nesiyezi, ikhanda, kanye nezinkinga zokuphefumula. Kodwa-ke, le ngozi ingagwenywa ngokusebenzisa umkhiqizo endaweni enomoya owanele futhi uvikele ukubonakaliswa isikhathi eside.
Ngaphandle kwalezi zingozi ezingaba khona, i-tetrahydroforunan ingumkhiqizo owusizo kakhulu. Isetshenziswa kakhulu embonini yezemithi njenge-solvent yezithako ezisebenzayo. Kubuye kube yi-solvent ebalulekile ekukhiqizweni kwama-polymers namapulasitiki, lapho kunika amandla ukulawula okuqondile ngezimo zokucubungula kanye nezindawo zokugcina zomkhiqizo.
Ngaphezu kwalokho, lo mkhiqizo kulula ukuphatha futhi unobuthi obuphansi. Kuboniswe ukuthi kube namazinga aphansi wobuthi ezifundweni ezifuywayo ezilwaneni, okwenza kube kuphephile ukusetshenziswa ezinqubweni zokukhiqiza ezilawulwayo. Lo mkhiqizo ubuye ube yi-biodegradable, okusho ukuthi ihlukana ngokwemvelo ibe yizinto ezingenabungozi ngokuhamba kwesikhathi.
Ekuphetheni, ngenkathi kunezingozi ezihambisana nazoTetrahydroforunan, lezi zingozi zingalawulwa ngokulandela izinqubo zokuphatha nezinqubo zokugcina. Ngokusebenzisa kwayo okusakazekile emikhakheni ehlukahlukene kanye nobuthi bayo obuphansi, i-TetrahyDroforunan ngumkhiqizo ophephile futhi obalulekile odlala indima ebalulekile ezinqubweni zesimanje zokukhiqiza. Uma nje kusetshenziswa kahle, asikho isizathu sokukubheka njengomkhiqizo oyingozi.
