Mayelana ne-RUNTAI

Izinhlanganisela zethu zifanele ukubunjwa kokucindezelwa futhi zitholakala ngempushana nangendlela eyimbudumbudu.

Izinhlanganisela zethu zokubumba i-melamine zifanelekile ekubunjweni kokucindezelwa futhi zitholakala ziyimpushana futhi ziyi-granular.

I-Paraformaldehyde iyi-white, crystalline solid ewuhlobo lwe-polymeric ye-formaldehyde, ehlanganisa amaketanga aqondile ama-molecule e-formaldehyde. Ikhiqizwa nge-polymerization yegesi ye-formaldehyde, ngokuvamile ngaphansi kokushisa nezimo ezithile. I-Paraformaldehyde iyancibilika emanzini futhi ingakhishwa i-depolymerized ibuyele ku-formaldehyde lapho ishiselwa noma iphathwa ngama-asidi noma izisekelo. Ivamise ukusetshenziswa ezinhlelweni ezahlukahlukene zezimboni, okubandakanya ukukhiqizwa kwama-resin, njenge-phenolic kanye ne-urea-formaldehyde resins, asetshenziswa ekunamatheleni, ekuhlanganisweni nasezintweni eziyinhlanganisela. Ukwengeza, i-paraformaldehyde isebenza njengesibulala-magciwane nesilondolozayo kumalabhorethri nasezilungiselelweni zezokwelapha ngenxa yezakhiwo zayo ezisebenzayo zokulwa namagciwane. Ibuye isetshenziswe ku-histology ukuze kulungiswe izicubu.

I-Melamine glazing powder iyisici se-thermosetting esisetshenziswa ekukhiqizeni i-melamine tableware kanye ne-dinnerware. Isetshenziswa njengendwangu yokuhlobisa nokuvikela ebusweni bezinto ze-tableware, ihlinzeka ngokuqeda okucwebezelayo futhi okuhlala njalo. Le mpushana yaziwa ngekhono layo lokuthuthukisa ukubukeka kwemikhiqizo ngenkathi inikeza ukumelana nemihuzuko, amabala, nokushisa.

I-Urea formaldehyde resin iyi-resin yokwenziwa ye-thermosetting ekhiqizwa ukusabela kwe-urea ne-formaldehyde, evame ukusetshenziswa njengento enamathela ezintweni eziyinhlanganisela esekwe ngokhuni. Ibonisa amandla aphezulu, ukumelana namanzi, nokumelana nokushisa.

I-Phenolic resin, noma i-phenol-formaldehyde resin, i-polymer yokwenziwa eyenziwe nge-polymerization ye-phenol ne-formaldehyde. Kuyi-thermosetting material eyaziwa ngamandla ayo aphezulu, ukuqina, nokumelana nokushisa namakhemikhali. Ngokujwayelekile isetshenziswa ezintweni zokunamathisela, okokuhlanganisa, nezinto eziyinhlanganisela, i-phenolic resin ihlonishwa ngezakhiwo zayo ezinhle kakhulu zemishini kanye nokushwabana okuphansi ngesikhathi sokwelashwa. Inqubo yokwelapha ihlanganisa ukushisa kanye/noma izinto ezibangela ukuba kube nomkhiqizo oqinile, ongaguquki. Izicelo zayo zisukela ekubopheni ngokhuni kuye ekufakweni kukagesi, okwenza kube ukukhetha okuhlukahlukene emikhiqizweni eyahlukene yezimboni nezabathengi.

Okunamatheliswa kwefilimu okupakisha kuyizinto zokunamathela ezikhethekile ezisetshenziselwa ukuhlanganisa izingqimba zamafilimu okupakisha ndawonye, ​​​​okuhlinzeka ngobuqotho besakhiwo, izakhiwo zesithiyo, kanye nokukhanga kobuhle kumkhiqizo wokugcina wokupakisha. Lezi zinto zokunamathisela zibalulekile ekukhiqizeni amaphakheji aguquguqukayo, asetshenziswa kakhulu ezimbonini zokudla, ezemithi, kanye nezimpahla zabathengi.

I-mineral oil defoamers wuhlobo lwe-ejenti ye-antifoaming esetshenziselwa ukulawula nokunciphisa ukwakheka kwegwebu ezinkambisweni ezihlukahlukene zezimboni kanye nokwakhiwa. Lawa ma-defoamers asekelwe kuwoyela wamaminerali, okuwumkhiqizo wokucwengisiswa kwe-petroleum.

Ama-ammonium salt dispersants awuhlobo lwe-ejenti ehlakazayo esebenzisa usawoti we-ammonium ukusiza ukusabalalisa izinhlayiya eziqinile ngokulinganayo ngaphakathi kwendawo ewuketshezi. Lawa ma-dispersants asebenza kahle kakhulu ezinhlelweni ezisekelwe emanzini futhi asetshenziswa ezimbonini ezahlukahlukene, ezihlanganisa okokugqoka, oyinki, okobumba, kanye nezolimo.

Izithasiselo Ezisekelwe Emanzini yizinto ezincibilika noma ezihlakazwe emanzini ukuze kuthuthukiswe izakhiwo nokusebenza kwemikhiqizo nezinqubo ezihlukahlukene.

I-Formaldehyde iwumkhiqizo wamakhemikhali omningi osetshenziswa kabanzi, inqubo elula yokukhiqiza kanye nokunikezwa okwanele kwezinto ezingavuthiwe. I-formaldehyde ibonakala iyigesi engenambala enephunga elinamandla, elinukayo.

I-Acrylic acid-based swelling thickeners wuhlobo lwe-rheology modifier esetshenziselwa ukwandisa i-viscosity futhi ithuthukise ukuthungwa kokwakheka okuhlukahlukene, ikakhulukazi kumasistimu asekelwe emanzini. Lawa ma-thickeners asuselwa ku-acrylic acid kanye nokuphuma kwawo, futhi asebenza ngokuvuvuka emanzini ukuze akhe isakhiwo esifana nejeli.
