- Ingemuva nokubukezwa
I-resin ye-melamine formaldehyde eguquliwe, eyaziwa nangokuthi i-melamine formaldehyde resin noma i-melamine resin, iyinhlanganisela ebalulekile ye-triazine ring. Ingumkhiqizo owenziwe ngokungezwa kwe-melamine ne-formaldehyde, bese ikhishwa amanzi emzimbeni bese iqiniswa. I-resin ye-Melamine inokumelana okuhle kwamanzi, ukumelana nokuguga, ukumelana nomlilo, ukumelana nokushisa, ukumelana nokugqwala kwamakhemikhali kanye nezakhiwo zokushisa. Ingasetshenziswa ekwenziweni kwepulasitiki ebunjiwe (izinto zokudla zansuku zonke nezinto zikagesi), amabhodi okwenziwa (i-plywood, phansi kokhuni olunamathelisiwe kanye namabhodi epulasitiki anamathelisiwe) kanye ne-foam. Ngaphandle kwalokho, i-resin ye-melamine isetshenziswa kabanzi njenge-coating, i-wood adhesive, i-paint cross-linking agent, i-fiber textile finishing agent, i-paper wet strength agent kanye ne-cement cement yokunciphisa amanzi nge-cement, njll.
- II. Isicelo
- Isicelo embonini yesikhumba
Embonini yesikhumba, i-melamine resin ivame ukusetshenziswa njenge-pre-tanning, retanning kanye ne-resin yokugcwalisa, phakathi kwayo i-trihydroxymethyl melamine resin isetshenziswa kakhulu kunazo zonke i-amino resin. Ama-amino resins anomshini wokushuka ofana nowokushuka kwe-aldehyde: i-prepolymer ingena esikhumbeni, futhi njengoba inani le-pH lincipha, i-prepolymer ijiya ngokuzenzakalelayo ibe ama-molecule anosayizi othile ngaphakathi kwesikhumba. Bese, i- -NHCH 2 OH esebenzayo kumolekyuli ihlangana neqembu le-amino kuketango le-collagen peptide, yakhe isistimu ehlangene exhunywe ngokuphambana ngezinjongo zokushuka. Ngesikhathi esifanayo, i-amino resin inomphumela wokugcwalisa. Ngezindlela zokuhlola, kutholakala ukuthi le resin inazo zombili izici zokushuka kanye nokugcwalisa, futhi ingagcwaliswa phakathi kwemicu ye-collagen yesikhumba ngobuningi ukuze kuzuzwe umphumela wokwenza umzimba wesikhumba ugcwale.
I-Melamine resin ukushuka i-ejenti isetshenziswa ekwenziweni kabusha kwesikhumba esikhanyayo se-chrome, esingenza isikhumba esiqediwe sibe nokusanhlamvu okuningiliziwe, umzimba ogcwele namathambo, ukuqina okusobala, umphumela omuhle wokuba mhlophe nokumelana nokukhanya okuhle. Futhi inokuhambisana okuhle namanye ama-ejenti okushuka. Uma isetshenziswe ngokuhambisana ne-ejenti yokushuka kwemifino, ingakhuthaza ukungena nokumuncwa kwe-ejenti yokushuka kwemifino futhi yandise ukumelana nokuguga kanye nokumelana nesimo sezulu kwesikhumba. Uma isetshenziselwa ukuvuselelwa kwe-suede, umphumela wenqwaba muhle.
- Isicelo embonini yamaphepha
Isetshenziswa njengesithuthukisi esimanzi, isimiso se-ejenti elwa namanzi kanye nezici zokusebenza ngoba inhlaka ye-melamine formaldehyde iqukethe i-hydroxymethyl, ingakha ukwakheka kwe-etherification phakathi kwenqwaba yefiber. Lokhu cross-oxhumanisa phakathi kwama-molecule ahlukene futhi akhiqize ukumelana kwamanzi, ukuze ishidi iphepha ukuthola umphumela amandla umswakama, ngakho embonini iphepha ngokuyinhloko isetshenziswa njengendlela eqinisa ejenti ezimanzi, ejenti anti-amanzi. Esetshenziswa embonini yokwenza iphepha ikakhulukazi i-hydroxymethyl melamine, kodwa ngenxa yokuzinza kwayo, ukuncibilika kwamanzi kanye nokuqukethwe kwamahhala kwe-formaldehyde akufanelekile futhi kunomthelela omubi ekumhlopheni nasekuqineni kwephepha, manje isetshenziswa kabanzi i-resin eguquliwe.
- Isetshenziswa njenge-ceramic kanye ne-disperant ye-cement
I-Melamine formaldehyde resin sulfonate iyi-anionic surfactant enhle, enomsebenzi ongaphezulu kanye nezinye izinto ezibalulekile, evame ukusetshenziswa ekhaya naphesheya njengezitsha zobumba, usimende, ukhonkolo ku-disperant ephumelelayo noma i-ejenti yokunciphisa amanzi. Indlela yayo yokusebenza ikakhulukazi: lolu hlobo lwe-ejenti yokunciphisa amanzi lune-adsorption kanye nokusabalalisa kanye nokugcoba, ngakho-ke ukusetshenziswa kwamanzi amancane kungathuthukisa ukuhambisana kokhonkolo, ukuze kufezeke inhloso yokunciphisa amanzi. Njengoba isilinganiso sokuxuba amanzi sincipha, ama-pores kukhonkolo ayancipha, okwenza usimende ube mkhulu futhi andise amandla, okungase futhi kunciphise inani likasimende. Ngenxa yokungenwa kwe-ejenti yokunciphisa amanzi, imikhiqizo ye-cement hydration ikhula kancane, isakhiwo se-mesh ye-sulfonated mesh siminyene kakhulu, okuvumela ukwanda kwamandla esikhathi eside kakhonkolo.
- Isetshenziswa njenge-adhesive yokhuni
Embonini yezinkuni, i-melamine formaldehyde resin isetshenziswa kakhulu njengesinamathelisi. Njengoba inomsebenzi omkhulu wamakhemikhali, ekungeneni emikhiqizweni yezinkuni, isivinini sokuqina kokuxhumanisa siyashesha. Ngaphansi kwesimo sokuthi akudingeki esinye isinamathelisi, singaqiniswa ngokushisa noma siqiniswe ngokushisa kwegumbi, ngaleyo ndlela sikhiqize umphumela wokubopha. Ngenxa yokuqina kwayo kokushisa, ukumelana namanzi, kanye nokumelana namakhemikhali, isetshenziswa kabanzi ebhodini lokwenziwa, okhunini, ekwakheni, ekupakisheni amaphepha, nakwezinye izinkambu. Ukugxila kulo mkhakha ikakhulukazi endleleni yokunqoba lesi simo sokuqhekeka nokuthola i-melamine formaldehyde resin eguquguqukayo ngokulinganisela, futhi ikhambi lamanje linjengokufaka i-polyvinyl alcohol. Ngoba ingasabela ne-formaldehyde ukukhiqiza i-polyvinyl alcohol methanol, esatshalaliswa ngokulinganayo ku-resin ukuvimba ama-molecule e-MF resin kuma-molecule e-triazole eduze nokudlala umphumela wokuqina, ukuvimbela ukuqhekeka.
- Isetshenziswa njenge-ejenti yokuqedela yokuphrinta nokudaya
Embonini yendwangu, i-melamine formaldehyde resin kanye ne-derivatives yizinto ezibalulekile zokulungiswa kwendwangu yokunyathelisa kanye nama-ejenti wokuqeda ukudaya. Indlela yokusebenza kwayo ikakhulukazi njenge-modifier ebusweni kanye ne-ejenti yokuhlanganisa izindwangu, ngaleyo ndlela ithuthukise ukusebenza kwezindwangu zikakotini mayelana nokuvimbela ukushwabana, ukuvimbela imibimbi nokumelana nokugeza. Kodwa-ke, ngenxa yokungaqini kahle kwesitoreji, umphumela wendwangu uzizwa unzima futhi kulula ukumunca ukuphuzi kwe-chlorine nokunye ukushiyeka, ukuguqulwa kocwaningo lwayo nakho kuyanda. Ukusetshenziswa kwamanje kwe-methanol etherification ye-melamine resin, kwengeza i-cyclic vinylidene urea, i-borax nezinye izilungisi ze-formaldehyde ukuze kutholwe ukuqina okuphezulu kwe-aldehyde eguquliwe ye-melamine formaldehyde resin finishing agent. I-resin eguquliwe isetshenziselwa i-poplin e-bleached ukuvimbela ukushwabana nokuqeda ukushwabana, ukulimala okuphuzi kanye ne-chlorine kungathuthukiswa, ukumelana nokugeza nakho kungcono. I-resin eguquliwe yayisetshenziselwa ukuqeda ukushwabana nokuqeda imibimbi kwe-poplin ebleached.
