Mapangidwe athu ndi oyenerera kuumba kwa kuponderezedwa ndipo amapezeka mu ufa ndi mawonekedwe a granular.

Mapangidwe athu opangira melamine ndi oyenera kupangira psinjika ndipo amapezeka muufa komanso mu mawonekedwe a granular.

Paraformaldehyde ndi yoyera, yolimba ya crystalline yomwe ndi mtundu wa polymeric wa formaldehyde, wopangidwa ndi maunyolo ozungulira a mamolekyu a formaldehyde. Amapangidwa kudzera mu polymerization ya mpweya wa formaldehyde, nthawi zambiri pansi pa kutentha ndi zina. Paraformaldehyde imasungunuka m'madzi ndipo imatha kuchotsedwanso kukhala formaldehyde ikatenthedwa kapena kuthandizidwa ndi ma acid kapena maziko. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza kupanga utomoni, monga ma phenolic ndi urea-formaldehyde resins, omwe amagwiritsidwa ntchito pomatira, zokutira, ndi zida zophatikizika. Kuonjezera apo, paraformaldehyde imagwira ntchito ngati mankhwala ophera tizilombo komanso osungira m'ma laboratories ndi makonzedwe azachipatala chifukwa cha mphamvu zake zowononga tizilombo. Amagwiritsidwanso ntchito mu histology pofuna kukonza minofu.

Melamine glazing ufa ndi zinthu zopangira thermosetting zomwe zimagwiritsidwa ntchito popanga melamine tableware ndi dinnerware. Amagwiritsidwa ntchito ngati zokongoletsera ndi zotetezera pamwamba pa zinthu za tableware, zomwe zimapereka mapeto onyezimira komanso okhazikika. Ufawu umadziwika chifukwa cha kuthekera kwake kukulitsa mawonekedwe azinthu pomwe umapereka kukana kukwapula, madontho, ndi kutentha.

Urea formaldehyde resin ndi utomoni wopangira thermosetting womwe umapangidwa ndi urea ndi formaldehyde, womwe umagwiritsidwa ntchito ngati zomatira muzinthu zopangidwa ndi matabwa. Imawonetsa mphamvu zambiri, kukana madzi, komanso kukana kutentha.

Phenolic utomoni, kapena phenol-formaldehyde utomoni, ndi kupanga polima wopangidwa mwa polymerization wa phenol ndi formaldehyde. Ndizinthu zopangira thermosetting zomwe zimadziwika ndi mphamvu zake zapamwamba, zolimba, komanso kukana kutentha ndi mankhwala. Zomwe zimagwiritsidwa ntchito pomatira, zokutira, ndi zida zophatikizika, utomoni wa phenolic ndi wamtengo wapatali chifukwa cha makina ake abwino kwambiri komanso kuchepa pang'ono pakuchiritsa. Kuchiritsa kumaphatikizapo kutentha ndi/kapena zoyambitsa, zomwe zimapangitsa kuti pakhale chinthu cholimba, chosasinthika. Ntchito zake zimachokera ku zomangira matabwa mpaka kusungunula kwamagetsi, zomwe zimapangitsa kukhala chisankho chosunthika pazinthu zosiyanasiyana zamafakitale ndi ogula.

Zomata zamakanema zomata ndi zomatira zapadera zomwe zimagwiritsidwa ntchito kumangiriza zigawo zamakanema onyamula palimodzi, kupereka kukhulupirika kwamapangidwe, zotchinga, komanso kukopa kokongola kuzinthu zomaliza. Zomatirazi ndizofunikira kwambiri popanga ma CD osinthika, omwe amagwiritsidwa ntchito kwambiri m'makampani azakudya, azamankhwala, komanso ogulitsa zinthu.

Mineral oil defoamers ndi mtundu wa antifoaming wothandizira omwe amagwiritsidwa ntchito kuwongolera ndi kuchepetsa kupangika kwa thovu munjira zosiyanasiyana zamafakitale ndi mapangidwe. Ma defoamers awa amachokera ku mafuta amchere, omwe amapangidwa ndi kuyeretsa mafuta.

Ammonium salt dispersants ndi mtundu wa mankhwala obalalitsa omwe amagwiritsa ntchito mchere wa ammonium kuti athandize kugawa tinthu tolimba mofanana m'kati mwa madzi. Ma dispersants amenewa amagwira ntchito makamaka pamadzi ndipo amagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo zokutira, inki, zoumba, ndi ulimi.

Zowonjezera Zomwe Zimapangidwa ndi Madzi ndi zinthu zomwe zimasungunuka kapena kumwazikana m'madzi kuti ziwonjezere mphamvu ndi magwiridwe antchito azinthu zosiyanasiyana.

Formaldehyde ndi mankhwala ochuluka omwe amagwiritsidwa ntchito kwambiri, njira zosavuta zopangira komanso zopangira zokwanira. Formaldehyde imawoneka ngati mpweya wopanda mtundu wokhala ndi fungo lamphamvu komanso lonunkhira.

Acrylic acid-based kutupa thickeners ndi mtundu wa rheology modifier womwe umagwiritsidwa ntchito kuonjezera mamasukidwe akayendedwe ndikusintha mawonekedwe amitundu yosiyanasiyana, makamaka pamakina otengera madzi. Zokhuthala izi zimachokera ku acrylic acid ndi zotumphukira zake, ndipo zimagwira ntchito potupa m'madzi kupanga mawonekedwe ngati gel.
