I-Polytheate Pollol (PPG)Uhlobo lwezinto ezibonakalayo ze-polymer ezinokumelana kahle nokushisa okuhle kakhulu, ukumelana ne-acid, kanye nokuphikiswa kwe-alkali. Kusetshenziswa kabanzi emikhakheni efana nokudla, ezokwelapha, ne-elekthronikhi, futhi kuyingxenye ebalulekile yezinto zokwenziwa zanamuhla zokwenziwa.
Ngaphambi kokuthenga ama-polytheth, kuyadingeka ukuqonda ukuthi kuyini. I-Polyberet iyisitayela se-polymer epulasitiki esikhulu esingatholakala ngokusabela kwe-polymerization. I-polynere inezinto eziqinile ezinjengokumelana nokushisa, ukumelana i-oxidation, i-acidation kanye nokuphikiswa kwe-alkali, kanye nokumelana kawoyela, okwenza kusetshenziswe kabanzi ekwenziweni kwemikhiqizo ehlukahlukene yezimboni nezezezezimboni.
Ngakho-ke singayithenga kuphi ikhwalithi ye-polyleate? Njengamanje, kunabahlinzeki abaningi be-polyther, futhi ingathengwa ngeziteshi ezahlukahlukene, njenge-Intanethi, izinkampani zokuhumusha, kanye nabathengisi. Lapho ukhetha umphakeli, amaphuzu alandelayo kufanele abhekwe:
Umhlinzeki Wezikweletu
Ngaphambi kokuthenga ama-polytheth, kubalulekile ukuqonda ukuthi umphakeli werekhodi lesikweletu, kufaka phakathi amarekhodi awo adlule okuthengiselana, ukuhlola ukuthembeka kwabo futhi aqinisekise ukuphepha nokusebenza kahle kokuthenga.
Ikhwalithi Yomkhiqizo Yomhlinzeki
Ikhwalithi yeI-Polytheate Pollol (PPG)Kuthinta ngqo ngqo ukuphepha nokusebenza kwemikhiqizo. Ngakho-ke, ukukhetha umphakeli othembekile kungaqinisekisa ikhwalithi yomkhiqizo futhi uthuthukise ukusebenza komkhiqizo.
Uhlelo lwensiza ye-Subsed umphakeli
Ukuthenga ama-polynee akusho nje kuphela kudinga ikhwalithi yomkhiqizo ethembekile kepha futhi kudinga umphakeli ukuthi ahlinzeke ngempumelelo nensizakalo yokuthengisa ngemuva kokuqinisekisa ukusetshenziswa okujwayelekile kwemikhiqizo.
Ngemuva kokuqonda indlela yokukhetha umphakeli, ungaqala inqubo yokuthengwa kwempahla ye-polythelekile. Izinyathelo zokuthenga ama-polynere zimi ngokulandelayo:
Nquma inani kanye nokucaciswa okuzothengwa
Okokuqala, nquma inani kanye nokucaciswa kwe-polyther okuzothengwa ngokususelwa kwizidingo zomkhiqizo nezidingo zangempela.
Xhumana nomphakeli futhi uthole isilinganiso
Ngemuva kokukhetha umphakeli ofanele, xhumana nabo ngocingo, i-imeyili, noma amapulatifomu we-inthanethi ukucela imininingwane eningiliziwe kanye namanani e-polythelekile.
Qhathanisa izingcaphuno nezinsizakalo
Ngemuva kokuthola izingcaphuno ezivela kubahlinzeki abaningi, qhathanisa amanani nezinsizakalo ezinikezwa ngabathengisi abahlukahlukene ukunquma ukuthi iyiphi ehlangabezana nezidingo zakho zokuthengwa.
Sayina inkontileka yokuthenga
Ngemuva kokuphothula umphakeli, inkontileka yokuthenga idinga ukusayinwa ukuqinisekisa amalungelo nezinzuzo zawo womabili amaqembu.
Ukukhokha nokulethwa
Ngemuva kokusayina inkontileka yokuthenga, yenza inkokhelo ngokuya ngemigomo okuvunyelwene ngayo. Lapho umphakeli ethola inkokhelo, azohlelela ukuthunyelwa kwama-polytheth.
Ngokufingqwa, UkuthengaI-Polytheate Pollol (PPG)Kudinga umzamo othile nesikhathi, kepha inqobo nje uma uthola umphakeli ofanelekile, ungaqinisekisa ikhwalithi yomkhiqizo nokusebenza. Ngokwengeziwe, kufanele kubhekwe ngokucophelela kufanele kunikezwe ekukhetheni kwabahlinzeki kanye namalungiselelo okukhokha ukuze kuqinisekiswe inqubo yokuthengwa kwempahla engenabungozi futhi engenaphutha.
