Paraformaldehyde yog dawb, crystalline khoom uas yog ib daim ntawv polymeric ntawm formaldehyde, muaj xws li linear chains ntawm formaldehyde molecules. Nws yog tsim los ntawm polymerization ntawm formaldehyde gas, feem ntau nyob rau hauv tshav kub thiab tej yam kev mob. Paraformaldehyde yog soluble hauv dej thiab tuaj yeem depolymerized rov qab rau hauv formaldehyde thaum rhuab los yog kho nrog acids lossis bases. Nws yog feem ntau siv rau hauv ntau daim ntawv thov kev lag luam, suav nrog kev tsim cov resins, xws li phenolic thiab urea-formaldehyde resins, uas yog siv rau hauv cov nplaum, coatings, thiab cov ntaub ntawv sib xyaw. Tsis tas li ntawd, paraformaldehyde ua cov tshuaj tua kab mob thiab khaws cia hauv cov chaw kuaj mob thiab chaw kho mob vim nws cov khoom siv tshuaj tua kab mob zoo. Nws kuj tseem ua haujlwm hauv histology rau kev kho cov ntaub so ntswg.

Melamine glazing hmoov yog cov khoom siv thermosetting siv hauv kev tsim cov melamine tableware thiab dinnerware. Nws yog siv los ua cov khoom siv kho kom zoo nkauj thiab tiv thaiv txheej rau saum npoo ntawm cov khoom siv rooj tog, muab cov glossy thiab ruaj khov. Cov hmoov no paub txog nws lub peev xwm los txhim kho cov tsos ntawm cov khoom thaum muab kev tiv thaiv rau khawb, stains, thiab cua sov.

Urea formaldehyde resin yog ib qho thermosetting hluavtaws cob uas tsim los ntawm cov tshuaj tiv thaiv ntawm urea thiab formaldehyde, feem ntau siv los ua cov nplaum hauv cov ntaub ntawv ntoo. Nws nthuav tawm lub zog siab, dej tsis kam, thiab kub tsis kam.

Phenolic resin, los yog phenol-formaldehyde resin, yog ib qho hluavtaws polymer tsim los ntawm polymerization ntawm phenol thiab formaldehyde. Nws yog cov khoom siv thermosetting paub txog nws lub zog siab, ua haujlwm ntev, thiab ua haujlwm rau cov cua sov thiab tshuaj. Feem ntau siv rau hauv cov nplaum, coatings, thiab cov ntaub ntawv sib xyaw, phenolic resin muaj nuj nqis rau nws cov khoom siv zoo heev thiab qis qis thaum kho. Cov txheej txheem kho muaj cov cua sov thiab / lossis cov catalysts, uas ua rau cov khoom siv tawv, tsis muaj zog. Nws cov ntawv thov sib txawv los ntawm kev sib txuas ntawm ntoo mus rau hluav taws xob rwb thaiv tsev, ua rau nws muaj ntau yam kev xaiv hauv ntau yam khoom siv thiab khoom siv.

Ntim zaj duab xis adhesives yog tshwj xeeb adhesives siv los khi cov khaubncaws sab nraud povtseg ntawm ntim zaj duab xis ua ke, muab cov qauv kev ncaj ncees, barrier zog, thiab aesthetic thov mus rau lub kawg ntim khoom. Cov nplaum nplaum no yog qhov tseem ceeb hauv kev tsim cov ntim khoom siv tau yooj yim, uas yog siv dav hauv cov khoom noj, tshuaj, thiab cov khoom siv khoom lag luam.

Mineral roj defoamers yog ib hom tshuaj tua kab mob uas siv los tswj thiab txo cov npuas dej hauv ntau cov txheej txheem kev lag luam thiab kev tsim. Cov defoamers no yog ua los ntawm cov roj ntxhia, uas yog cov khoom siv roj av refining.

Ammonium ntsev dispersants yog hom dispersing tus neeg sawv cev uas siv ammonium ntsev los pab faib cov khoom sib npaug ntawm cov kua nruab nrab. Cov dispersants no tshwj xeeb tshaj yog nyob rau hauv cov dej-raws li systems thiab yog siv nyob rau hauv ntau yam kev lag luam, xws li txheej, inks, ceramics, thiab kev ua liaj ua teb.

Dej-raws li additives yog cov khoom uas yaj los yog dispersed hauv dej los txhim kho cov khoom thiab kev ua tau zoo ntawm ntau yam khoom thiab cov txheej txheem.

Formaldehyde yog cov khoom siv tshuaj lom neeg nrog kev siv dav, txheej txheem tsim khoom yooj yim thiab txaus cov khoom siv raw. Formaldehyde zoo li cov roj tsis muaj xim nrog lub zog, pungent tsw.

Acrylic acid-based swelling thickeners yog ib hom kev hloov kho rheology siv los ua kom cov viscosity thiab txhim kho kev ntxhib los mos ntawm ntau yam formulations, tshwj xeeb tshaj yog nyob rau hauv cov dej-raws li systems. Cov thickeners no yog muab los ntawm acrylic acid thiab nws cov derivatives, thiab lawv ua haujlwm los ntawm o hauv dej los tsim cov qauv zoo li gel.
