I-paraformaldehyde (多聚甲醛) ne-hexamethylenetetramine (乌洛托品, eyaziwa nangokuthi i-methenamine) yizona ezimbili zamakhemikhali ezisebenza kakhulu futhi ezisetshenziswa kabanzi ekwenziweni kwezimboni zesimanje. Lezi zinhlanganisela zisebenza njengezinto ezibalulekile ezakhiweni ezindaweni eziningi, okubandakanya ukukhiqizwa kwezinhlanganisela zokwenziwa, imikhiqizo yokubulala amagciwane, amakhemikhali ezolimo, imithi, nemikhiqizo yamafutha aqinile. Ukuqonda izimfanelo eziyisisekelo, izindlela zokuhlanganisa, kanye nezinhlobonhlobo zezicelo zalezi zinto kubalulekile kunoma yiliphi ibhizinisi elihilelekile ekuthengeni amakhemikhali noma ekwakhiweni kwezimboni. I-Hebei Jintaida Chemical Co., Ltd., umphakeli omethembayo embonini yamakhhemikhali, yakhe idumela layo ngokuhlinzeka nge-paraformaldehyde (多聚甲醛) ne-hexamethylenetetramine (乌洛托品) ehlanzekile kumakhasimende emhlabeni wonke, iqinisekisa ikhwalithi engaguquki ehlangabezana nezindinganiso eziqinile zezimboni. Ubuhlobo obuhlangene phakathi kwezinhlanganisela ezimbili, zombili ezitholakala noma ezihlobene ne-formaldehyde chemistry, kubenza kube ukubhanqaniselwa kwemvelo kubakhiqizi abafuna izinto zokusetshenziswa ezithembekile zezinqubo zokukhiqiza eziyinkimbinkimbi.

I-Polyoxymethylene iyifomu eyenziwe ngama-polymer we-formaldehyde enefomula yamachiza ejwayelekile ethi HO(CH₂O)ₙH, lapho u-n uvamise ukuba kusuka kumayunithi angu-8 kuye ku-100, okuyinika izinga lokuhlanganisa elithinta izici zayo ezibonakalayo. Ngokungafani nezixazululo ze-formaldehyde ezisetshenziswa emanzini, eziqukethe amanzi amaningi nezinto ezizinzisa, i-paraformaldehyde ikhona njenge-solid elimhlophe elikristal elikhipha igesi ye-formaldehyde lapho ifudunyezwa noma i-depolymerized. Le fomu ye-solid inikeza izinzuzo ezinkulu mayelana nokuzinza, ukugxila, nokulula ukuphatha uma kuqhathaniswa nezinye izindlela ze-formaldehyde ezibukwayo. Isakhiwo samachiza siqukethe amayunithi aphindaphindayo e-oxymethylene agcina ngama-hydroxyl groups, adala i-polymer eliqondile elingakwazi ukuhlakazwa kalula ngaphansi kwezimo ezilawulwayo. Lesi sakhiwo esiyingqayizivele sivumela abakhiqizi ukuthi bathole i-formaldehyde engenamanzi ngokuyisisekelo ezicelo ezikhethekile lapho okuqukethwe umswakama kufanele kuncishiswe kakhulu.

Ukwenziwa kwezinto eziningi kwe-多聚甲醛 ngokuvamile kuhilela ukugxilisa nokulandelwa kokuhlanganiswa kwezixazululo zamanzi ze-formaldehyde ngokusebenzisa inqubo yokukhipha amanzi elawulwa ngokucophelela. Abakhiqizi baqala ngesixazululo se-formaldehyde esigxilisiwe, ngokuvamile cishe amaphesenti angu-30 kuya ku-50, futhi basuse amanzi ngaphansi kwezimo zokunciphisa umoya ngenkathi bengeza izinsiza ukuze kukhuthazwe ukuhlanganiswa. I-slurry eyenzekayo bese ipholiswa, ihlungwe, igezwe, futhi yomiswe ukuze kukhiqizwe umkhiqizo wokugcina omhlophe noma oyingqayizivele onokuqukethwe kwe-formaldehyde ngokuvamile kudlula amaphesenti angu-95. I-Hebei Jintaida isebenzisa ubuchwepheshe obuthuthukisiwe bokukhiqiza obuqinisekisa ukusabalala okungaguquki kosayizi wezinhlayiya namazinga aphezulu okuhlanzeka, ahlangabezana nezidingo eziqinile zezicelo ezisezingeni lemithi nezisezingeni lezimboni ngokufanayo. Ipharamitha yenqubo, okubandakanya izinga lokushisa, ingcindezi, kanye nokugxiliswa kwezinsiza, kufanele kuphathwe ngokunembayo ukuze kufezekiswe isisindo samamolekyuli esifunwayo kanye nezici zokuncibilika zezicelo zokugcina ezithile.

I-polyoxymethylene inezimfanelo eziningana ezihlukile zomzimba neze-keimiyali ezenza ibe yigugu kuyo yonke imikhakha yezimboni eyahlukene. Le nto ivela njengempuphu emhlophe eqinile noma amagranule anamakha anuka njenge-formaldehyde, futhi inezinga lokuncibilika eliphakathi kwama-degree Celsius angu-120 kuya ku-170 kuye ngesilinganiso sokuhlanganiswa. Iyancibilika kalula emanzini ashisayo nasezintweni ezi-organic ezi-polar njenge-methanol, i-ethanol, ne-acetone, kanti ibonisa ukuncibilika okulinganiselwe emanzini abandayo nasezintweni ezingezona ezise-polar. Ngokwe-keimiyali, i-paraformaldehyde isebenza njengomthombo olula we-formaldehyde engenamanzi, ikhipha i-monomer lapho ifudunyezwa noma ikhona ama-acids noma ama-bases, okwenza ukuthi isetshenziswe ezinhlotsheni zokuhlukaniswa kwe-polymerization ezilawulwayo. Le nto iphinde ibonise ukuzinza okuhle eshalofini lapho igcinwa kahle ezitsheni ezivaliwe kude nomswakama nokushisa, okwenza kube ukukhetha okusebenzayo ukugcinwa kwesikhathi eside kwezimboni kanye nezokuthutha.

I-Urotropin, eyaziwa ngokuthi i-hexamethylenetetramine futhi ngokuvamile ibizwa nge-methenamine emikhakheni yezemithi, iyinhlanganisela ye-organic heterocyclic eyenziwa ngokusebenzisa ukusabela kwe-formaldehyde ne-ammonia. Ukwenziwa kwayo okudala kuhilela ukwelapha i-formaldehyde esetshenziswa emanzini ne-ammonia solution egxilile ngaphansi kwezimo zokushisa ezilawulwa ngokucophelela, okuholela ekwakhekeni komkhiqizo we-crystalline onefomula ye-molecular C₆H₁₂N₄.
