I-POLYETHER POLYOL (PPG)luhlobo lwempahla ye-polymer ekwazi ukumelana nokushisa okuhle kakhulu, ukumelana ne-asidi, nokumelana ne-alkali. Isetshenziswa kakhulu emikhakheni efana nokudla, ezokwelapha, kanye ne-electronics, futhi iyingxenye ebalulekile yezinto zokwenziwa zesimanje.
Ngaphambi kokuthenga i-polyether, kubalulekile ukuqonda ukuthi kuyini. I-polyether iyinsimbi ye-polymer epulasitiki kakhulu engatholakala ngokusabela kwe-polymerization. I-polyether inezindawo eziqinile ezifana nokumelana nokushisa, ukumelana ne-oxidation, ukumelana ne-asidi ne-alkali, nokumelana nowoyela, okuyenza isetshenziswe kabanzi ekukhiqizeni imikhiqizo ehlukahlukene yezimboni neyomphakathi.
Pho singayithenga kuphi i-polyether yekhwalithi enhle?Okwamanje, baningi abahlinzeki be-polyether, futhi ingathengwa ngemigudu ehlukahlukene, njenge-inthanethi, izinkampani zokuhumusha, nabahwebi. Lapho ukhetha umphakeli, amaphuzu alandelayo kufanele acatshangelwe:
Irekhodi lesikweletu lomphakeli
Ngaphambi kokuthenga i-polyether, kubalulekile ukuqonda irekhodi lesikweletu lomphakeli, okuhlanganisa namarekhodi abo omsebenzi wesikhathi esidlule, ukuhlola ukwethembeka kwawo nokuqinisekisa ukuphepha nokusebenza ngempumelelo kokuthenga.
Ikhwalithi yomkhiqizo womphakeli
Izinga leI-POLYETHER POLYOL (PPG)kuthinta ngqo ukuphepha nokusebenza kwemikhiqizo. Ngakho-ke, ukukhetha umphakeli onokwethenjelwa kungaqinisekisa ikhwalithi yomkhiqizo futhi kuthuthukise ukusebenza komkhiqizo.
Isistimu yesevisi yangemuva kokuthengisa yomhlinzeki
Ukuthenga i-polyether akudingi nje kuphela ikhwalithi yomkhiqizo ethembekile kodwa futhi kudinga ukuthi umphakeli anikeze isevisi efika ngesikhathi neyochwepheshe ngemva kokuthengisa ukuze aqinisekise ukusetshenziswa okuvamile kwemikhiqizo.
Ngemva kokuqonda indlela yokukhetha umphakeli, ungaqala inqubo yokuthenga i-polyether. Izinyathelo zokuthenga i-polyether zimi kanje:
Nquma inani kanye nemininingwane okufanele ithengwe
Okokuqala, thola inani kanye nokucaciswa kwe-polyether okufanele ithengwe ngokusekelwe ezidingweni zomkhiqizo kanye nezidingo zangempela.
Xhumana nomphakeli bese uthola ikhotheshini
Ngemva kokukhetha umphakeli ofanelekayo, xhumana naye ngocingo, i-imeyili, noma izinkundla ze-inthanethi ukuze ucele imininingwane enemininingwane namanani entengo ye-polyether.
Qhathanisa izingcaphuno namasevisi
Ngemva kokuthola amakhotheshini kubahlinzeki abaningi, qhathanisa amanani namasevisi ahlinzekwa abahlinzeki abahlukahlukene ukuze unqume ukuthi iyiphi engahlangabezana kangcono nezidingo zakho zokuthenga.
Sayina inkontileka yokuthenga
Ngemva kokuphothula umphakeli, inkontileka yokuthenga idinga ukusayinwa ukuze kuqinisekiswe amalungelo nezinzuzo zazo zombili izinhlangothi.
Inkokhelo nokulethwa
Ngemva kokusayina inkontileka yokuthenga, yenza inkokhelo ngokwemibandela okuvunyelwene ngayo. Uma umphakeli ethola inkokhelo, bazohlela ukuthunyelwa kwe-polyether.
Kafushane, ukuthengaI-POLYETHER POLYOL (PPG)kudinga umzamo nesikhathi, kodwa inqobo nje uma uthola umphakeli ofanelekayo, ungaqinisekisa izinga lomkhiqizo nokusebenza. Ukwengeza, kufanele kucatshangelwe ngokucophelela ukukhethwa kwabahlinzeki kanye namalungiselelo okukhokha ukuze kuqinisekiswe inqubo yokuthenga engenabungozi futhi engenaphutha.
