Ukuthuthukiswa Komkhiqizo Omusha: Ukubambisana namaqembu akho e-R&D ukuthuthukisa izixazululo ezintsha ze-polyurethane zezitayela zezicathulo zesikhathi esizayo kanye nezinhlelo zokusebenza ezikhethekile.

Ikhwalithi Nokungaguquguquki:

Silandela izinyathelo eziqinile zokulawula ikhwalithi kuyo yonke inqubo yethu yokukhiqiza, siqinisekisa ukuthi yonke inqwaba yama-catalyst nama-surfactants ethu, kufaka phakathi i-MXS-6, ihlangabezana nezindinganiso eziphakeme kakhulu zemboni. Lokhu kuzibophezela okungaguquki kwikhwalithi kuqinisekisa ukusebenza okuqhubekayo ekukhiqizweni kwakho kwe-PU sole, okuholela ekhwalithini yomkhiqizo ethembekile kanye nokuguquguquka okuncishisiwe.

Izixazululo Zenziwe Ngokwezifiso:

Njengoba siqaphela ukuthi ukusetshenziswa kwezicathulo ngakunye kuhlukile, sinikeza ukuguquguquka kokuthuthukisa inhlanganisela ye-catalyst kanye ne-surfactant eyenziwe ngokwezifiso efanela izidingo zakho ezithile. Kungakhathaliseki ukuthi udinga ukufeza umuzwa othile, ukuthuthukisa isici esithile sokusebenza, noma ukuzivumelanisa nezinto ezintsha zokusetshenziswa, amakhono ethu e-R&D asenza sikwazi ukudala izixazululo ze-polyurethane ezenzelwe wena ezikunikeza inzuzo ehlukile yokuncintisana.

Ngokukhetha i-[Igama Lenkampani Yakho] njengomlingani wakho, uthola ukufinyelela kubuchwepheshe be-catalyst obusezingeni eliphezulu kanye nethimba elizinikele elizinikele ekukusizeni ukuthi usungule futhi uphumelele emakethe yezicathulo. Silapha ukusekela uhambo lwakho lokudala isizukulwane esilandelayo sezinyawo ze-polyurethane ezikhululekile, eziqinile, nezisebenza kahle kakhulu.

8. Isiphetho: Ukuqhubekela Phambili Ngezixazululo Ezithuthukisiwe Ze-Polyurethane

I-polyurethane sole iguqule ngokungenakuphikwa imboni yezicathulo, inikeza inhlanganisela engenakuqhathaniswa yenduduzo, ukuqina, ukwakheka okulula, kanye nokumuncwa okukhulu kokushaqeka. Inqubo eyinkimbinkimbi yokwakha lawa ma-sole asebenza kahle incike kakhulu ekulawuleni okunembile okunikezwa ama-catalyst nama-surfactant akhethekile. Njengoba kubonisiwe, ama-surfactant e-silicone afana ne-MXS-6 yethu (elingana ne-DC193) abaluleke kakhulu ekuhleleni i-polyurethane chemistry eyinkimbinkimbi eholela ekhwalithini ehambisanayo kanye nokusebenza kahle kwezicathulo.

I-MXS-6 ivelele njengengxenye ebalulekile kubakhiqizi abahlose ukukhiqiza ama-PU soli aphezulu ezinhlobonhlobo zezicelo, kusukela ezicathulweni ezivamile nezezemidlalo kuya ezicathulweni zokuphepha eziqinile namabhuzu. Amandla ayo okuthuthukisa ukulawulwa kwamaseli, ukuthuthukisa ukuhamba kwezinto, nokuqinisekisa ikhwalithi yobuso ngokuqondile ihumusha ibe umkhiqizo wokugcina ongcono kakhulu ohlangabezana nokulindelwe okufunwa ngabathengi banamuhla.

Kwa-MINGXU NEW MATERIALS, sizibophezele ekubeni phambili kwezixazululo ze-polyurethane embonini yezicathulo. Ukuzinikela kwethu ekhwalithini, kanye nobuchwepheshe bethu kanye nekhono lethu lezixazululo ezenziwe ngokwezifiso, kusibeka njengomlingani ofanele wabakhiqizi abafuna ukusungula izinto ezintsha nokwenza kahle. Ngokusebenzisa ubuchwepheshe obuthuthukisiwe be-catalyst njenge-MXS-6, ungaqinisekisa ukuthi ama-polyurethane soli akho anikeza induduzo, ukuqina, kanye nokusebenza okuhlukanisa izicathulo zakho.

Sikumema ukuthi uxhumane nathi ukuze uhlole ukuthi ama-catalyst ethu e-polyurethane nama-surfactant angakusiza kanjani ukuthi uqhubekele phambili ngokuzethemba, uthuthukise izinqubo zakho zokukhiqiza izicathulo futhi ulethe imikhiqizo emihle emakethe.
