-Ngenasibomiminto edliwayofOrmaldehyderiselayishikubizwa ngokuthiI-Melamine resin, obeye aziwe njengoI-Melamine Formatdehyde ResinnomaI-Melamine resin. Kuyinto ebalulekile ye-Triazine Ring Compound.I-Melamine Resininokumelana namanzi amahle kakhulu, ukumelana nokuguga, i-flame retardant, ukumelana nokushisa, ukumelana namakhemikhali kanye nempahla yokufaka, futhi kungasetshenziswa empahleni esekelwe ngokhuni (Plywood, ipulasitiki elihlanzayo Amabhodi)) ne-Foam Plastic, njll. Ngaphezu kwalokho, I-Melamine resinIsetshenziswa kabanzi njengezimbobo, ukunamathela kwezinkuni, ama-ejenti wokuxhumanisa ngokuwela, ama-ejenti wokuqeda ama-fiber textile, ama-ejenti wamandla wamanzi nama-ejenti wamandla we-cent agents ancs.

I-Melamine Resininezicelo ezinkulu ezilandelayo:

1. Isicelo embonini yesikhumba:

Embonini yesikhumba,I-Melamine resinkungukusetshenziswa kwangaphambili kwangaphambili, ukuphenywa nokugcwalisa i-resin, phakathi kwayo i-trimethylolI-Melamine resinyi-amino resin esetshenziswa kakhulu. I-Amino Resin inendlela yokuhamba ethambekele ethandweni le-Aldehyde Tanning: I-prefermer ingena esikhunjeni, futhi njengoba inani le-PH liyancipha, okuyisisekelo se-PROPYMer ngokuzenzakalela ku-molecule elinosayizi othile, kanye ne-active -nch 2 O futhi I-collagen ku-molecule idluliswa. Amaqembu we-Amino ecaleni le-peptide ancishiswe ukwakha uhlelo oluhlangene lokuxhumanisa ukufeza inhloso yokushunqa. Ngasikhathi sinye, i-Amino Resin inomphumela wokugcwalisa. I-Braum, ama-Aloysins nabanye basebenzisa i-GPS, iR, 1h-NMR, 13C-NMR nezinye izindlela zokutholwa, futhi bathola ukuthi le nsakhiwo ine-resin inakho konke okushukunyiswayo, futhi ingagcwaliswa ngemali enkulu phakathi kwezikhumba ezihlanganisiwe yenza umzimba wesikhumba. Umphumela.I-Melamine ResinI-Agent ye-Tanning isetshenziswa ekushintsheni kwesikhumba esikhanyayo se-Chrome-Tanted ukwenza isikhumba esiqediwe saqina, sigcwele amathambo, ukuqina okusobala, umphumela omuhle onzima nokushesha okusheshayo. Futhi inokuhambisana okuhle namanye ama-ejenti wokushuka. Kusetshenziswe ngokuhlanganiswa nama-ejenti wokuthatha imifino, kungakhuthaza ukungena nokutholwa kwabahlinzeki bemifino, futhi kwandise ukumelana nokuqina komzimba kanye nokumelana nesimo sezulu ngesikhumba. Uma isetshenziselwe ukubuyiselwa kwe-suede, umphumela wokuphakamisa ulungile.

2. Isicelo embonini yamaphepha:

Isimiso kanye nezimpawu zokusebenza zokusetshenziswa njenge-ejenti eqinisa amanzi kanye nompheme wamanzi. NgobaI-Melamine Formatdehyde ResinKuqukethe i-methylol, ingakha isakhiwo esinethelelekile phakathi kwezinqwaba zefayibha. Lokhu kuxhumanisa okuphambanisa phakathi kwama-molekyuli ahlukene kuveza ukumelana kwamanzi futhi kwenza iphepha lephepha. Ukufeza umphumela wamandla anomswakama, kusetshenziswa ikakhulukazi njenge-ejenti eqinisa amanzi kanye nompheme wamanzi embonini yamaphepha. I-Trimethylol Melamine isetshenziswa ikakhulukazi embonini yamaphepha, kepha ngoba ukuqina kwayo, ukuqina kwamanzi nokuqukethwe kwamahhala kwe-formaldehyde akulungile, futhi kunomphumela omubi ngokuqina kanye nokuqina kwephepha, i-melamine eguquliwe isetshenziswa kabanzi njengamanje. resin.

3. Kusetshenziswe njenge-Ceramic kanye ne-Cement Dispersant:

I-Melamine Formatdehyde ResinI-Sulfonate is a anionic ancactant enhle enomsebenzi ongaphezulu kanye nezinye izakhiwo ezibalulekile. Imvamisa isetshenziswa njenge-extarant esebenza kahle noma amanzi anciphisa amandla kuma-ceramics, usimende nokhonkolo ekhaya nakwamanye amazwe. Indlela yayo yesenzo ikakhulukazi: Lolu hlobo lwamanzi ancishisiwe lunemisebenzi ye-adcerption, ukuhlakazeka kanye nokuthambisa, ngakho-ke ukusebenziseka kokhonkolo kungathuthukiswa ngokusebenzisa amanzi amancane, ukuze kufinyelelwe inhloso yokunciphisa amanzi. Ngenxa yokwehla kwesilinganiso sokuxubana samanzi, ama-pores kukhonkolo ancishisiwe, okwenza usimende mkhulu ngokwengeziwe futhi andise amandla, anganciphisa futhi inani lesimende. Ngenxa yokungenela kwamanzi anciphisa i-ejenti, ukukhula kwemikhiqizo ye-Cement Hydration kuhamba kancane, futhi isakhiwo sekhonkrithethi sokhonkolo esinamathuna sinobunye, okuzuzisa ngokwanda kwamandla wesikhathi eside kakhonkolo.

4. Kusetshenziswe njengoba izinkuni zinamathelayo:

Embonini yezinkuni,sokuhlosiweminto edliwayofOrmaldehyderiselayishizisetshenziswa ikakhulukazi njengezinamathela. Ngenxa yomsebenzi wayo wamakhemikhali aphezulu, lapho ingena emikhiqizweni yezinkuni, ijubane lokuxhuma kanye nokuqina okuqinile lishesha, futhi lingaba nzima noma lukhuni ngaphansi kwamazinga okushisa angenazo ezinye izinkampani, ngaleyo ndlela kukhiqize umphumela onamandla. Ngenxa yokuqina kwayo okuhle okushisayo, ukumelana kwamanzi kanye nokumelana kwamakhemikhali, kusetshenziswa kabanzi kumaphaneli asuselwa kuzinkuni, izinkuni, ukwakhiwa, ukupakishwa kwamaphepha kanye nezinye izinkambu. Ukugxila kwale nkambu yindlela yokunqoba into ephukile futhi utholeI-Melamine Formatdehyde Resinngokuguquguquka okulinganiselayo. Isixazululo samanje ukwengeza utshwala be-polyvinyl, ngoba kungasabela nge-formaldehyde ukukhiqiza i-polyvinyl acetal, okusatshalaliswa ngokulinganayo ku-resin, ukuze ivimbele ama-molecule amathathu we-nItrogen vimbela ukuqhekeka.

I-5. Isetshenziswa njengokuphrinta kwendwangu nomenzeli wokudaya:

Embonini yezindwangu,sokuhlosiweminto edliwayofOrmaldehyderiselayishiFuthi izinto zayo ezifuywayo ziyizinto ezibalulekile eziluhlaza zokulungiselela ukuphrinta kwendwangu, ukudaya kanye nama-ejenti wokuqeda. Indlela yayo yesenzo isezosetshenziswa ikakhulukazi njenge-ejenti ye-revifier ne-coupling yendwangu, ngaleyo ndlela yenza ngcono ukushwabanisa, ukubhala kabusha kanye nemibimbi yokuwasha amanzi yezakhiwo zekotini. Kodwa-ke, ngenxa yokuqina okuyisitoreji, umuzwa wesandla esibi nokutholwa kwesandla okulula kwe-chlorine nokuphuzi kwendwangu ngemuva kwesicelo, kwenziwe ezinye izifundo ngokuguqulwa kwayo. Njengamanje, i-methanol etheliziweI-Melamine resiniyasetshenziswa, futhi i-formaldehyde modifiers efana ne-cyclic vinylidene urea ne-borax yengezwa ukuthola i-modifiedI-Melamine Formatdehyde ResinUmenzeli oqeda nge-Aldehyde ephansi ne-Aldehyde ephansi kanye nokuqina okuphezulu. I-resin eguquliwe isetshenziselwa ukubhala kabusha kanye nokulwa nokuwohloka kokuqedwa kwe-poplin okuhlanganisiwe, ukwehlisa umoya okuphuzi nokuhlanza, futhi ukumelana nokugeza kungcono futhi. Ngaphezu kwalokho, isikhathi sokugcina somenzeli wokuqeda singu-210-365 d, okuqukethwe kwamahhala kwe-formaldehyde kungu-0.3%, futhi okuqukethwe okuqinile kungama-40%.
