I-stiffener yendwangu iyinto ye-polymer yemvelo ethuthukisa ukubukeka kwendwangu, ikhulisa ukuqina nobunzima bendwangu, futhi iyinike umuzwa oqinile. Iyingxenye ebalulekile yezinsiza zokuqeda. Indwangu ephathwayo ingasetshenziswa kabanzi ezindwangu zokuhlobisa, ikakhulukazi indwangu yamakhethini, indwangu yesikhwama kanye nokukhiqizwa kwendwangu ehlanganisiwe. Iphinde isetshenziswe ekukhiqizeni i-interlining (i-fusible interlining kanye ne-resin interlining).
Emazweni athuthukile asentshonalanga, i-emulsion polyacrylate compounds ngenxa yentengo yayo ephansi, ukuhlanganiswa okulula, ukusebenza okuzinzile kanye nezinye izinzuzo embonini yokunyathelisa yendwangu nokudaya isetshenziswe kabanzi. I-stiffener esetshenziswa kakhulu yilezi: i-melamine resin, i-urea-formaldehyde resin, i-polyacrylate, i-polyvinyl acetate, i-polyvinyl alcohol nesitashi, kanye nemikhiqizo yazo eguquliwe.
Izinzuzo kanye nebubi bama-stiffeners
Igama | Izinzuzo | Okumbi |
I-Melamine resin | Ngemuva kokuqeda ukuqina kwendwangu, ukuncipha, ukunwebeka, ukuzizwa kungcono, ikakhulukazi umphumela wokuqina wokwenziwa kwe-fiber muhle. | Ngemva kokuphothula, indwangu kulula ukumunca umswakama, ubulukhuni nokuqina kokuncipha, ukuphuzi namandla ukwehla, ukukhululwa kwe-formaldehyde yamahhala, njll. Ukuqeda ukugcinwa kwe-ejenti ukuzinza akubi. |
Urea-formaldehyde resin | Ngemva kokuqeda, indwangu inokuqina okungcono kanye nezindleko zempahla eluhlaza ephansi. | Ngemva kokuphothula, indwangu ine-elasticity empofu, i-handfeel enamandla, i-shrinkage enkulu, ukumelana nokugeza okungalungile kanye nokukhululwa kwe-formaldehyde yamahhala. Ukungaqini kahle kwesitoreji se-ejenti yokuqedela. |
Ama-Polyacrylates kanye ne-polyvinyl acetates | Inezici zokumelana nokukhanya, ukumelana nokuguga futhi akukho ukuphuzi. Kulula ukuhlanganisa, ukuzinza okuhle kwesitoreji, akukhiqizi i-formaldehyde yamahhala. Ukuqina komphumela muhle, ikakhulukazi ekuqedeni ukuqina kwendwangu ye-cellulose fiber. | Inani elifanayo le-ejenti yokuqedela, umphumela wokuqina ezindwangu zokwenziwa ungaphansi kwe-melamine resin. Ngemva kokuqeda, indwangu ayinakho ukunwebeka kanye nomuzwa owugqinsi. I-Polyvinyl acetate ishwabene futhi inokumelana nesithwathwa okubi. |
Polyvinyl utshwala | Ine-rheology enhle futhi ingakha ifilimu enamandla amakhulu, enomphumela omuhle wokuqina kwendwangu ye-cellulose. | Kunzima ukwehlisa ngaphansi kwemvelo yemvelo futhi kungakha inani elikhulu legwebu emanzini. I-ejenti yokuqedela endwangu ngemuva kokushisa kulula ukuthambisa futhi ukopha, ukugezeka okubi. |
Isitashi esishintshiwe | Kulula ukuthola impahla eluhlaza, intengo ephansi, engagqwali, kulula ukuyisebenzisa, i-biodegradable, futhi ingenza indwangu ibe nomthelela omuhle wokuqina. | Ngemva kokuqeda, ukuqina kwendwangu kuncipha ngomswakama, futhi kulula ukuwohloka futhi kube yisikhunta. Ukungawashwa kahle, ukuzwa kwesandla esimaholo, nokunwebeka okubuthakathaka. |
Cubungula amaphuzu abalulekile
Inqubo yokugcoba inomthelela omkhulu ku-formaldehyde ebusweni bendwangu kanye nokuqina kwendwangu ngemva kokuqeda. Ngokukhula kwesikhathi sokuthosa kanye nezinga lokushisa lokuthosa, ukuqina kuyanda futhi okuqukethwe kwe-formaldehyde ebusweni bendwangu kuncipha kakhulu. Lapho inqubo yokucubungula ilawulwa ku-200 ° C×60s, i-formaldehyde esendwangu ingafinyelela ngaphansi kuka-75ppm.
Lokhu kungenxa yokuthi ngokuthuthukiswa kwenqubo yokomisa, ukuphambana kwe-stiffener kwanele, ngakho ukuqina kwendwangu ngemva kokuqeda kuyanda. Ngakolunye uhlangothi, i-formaldehyde emgqeni wokuqeda kulula ukuguquguquka ngaphansi kwezimo zokushisa eziphakeme, okuholela ku-formaldehyde ephansi kwendwangu yokugcina.
Kukhona ukusabela kokulingana okuguqukayo phakathi kwe- ejenti yokuqinisa kanye ne-formaldehyde. Ngokushintsha kwendawo yangaphandle (njenge: izinga lokushisa, umswakama, i-pH, njll.), i-formaldehyde izohlukaniswa njalo. Ngemva kokuqeda isampula yokuqala yendwangu, i-formaldehyde iphansi, njengoba isikhathi sokugcina sinwetshwa, i-formaldehyde yanda kancane kancane. Lapho isikhathi sokugcina sifika ezinsukwini eziyi-10-12, ukuzinza okuyisisekelo kwendwangu ye-formaldehyde.
Uma igcinwe endaweni engenawo umoya, i-formaldehyde ekhishiwe izonqwabelana kakhulu, kuzoba nomuzwa ohlabayo nonokhahlo. Kunconywa ukuthi indwangu ngemuva kokuqeda nge-resin eqinile kufanele igcinwe endaweni enomoya omuhle.
Izimo ezisebenzayo zohlobo ngalunye lwe-stiffener
- Indwangu kakotini ngemva kokuqeda ukuqina: i-polyvinyl alcohol > i-polyacrylate > isitashi > i-melamine resin.
- Indwangu ye-polyester ngemva kokuqeda ukuqina: i-polyvinyl alcohol > isitashi > i-melamine resin > i-polyacrylate.
- Ukushesha ukuwasha: i-polyacrylate > i-polyvinyl alcohol > i-melamine resin > isitashi.
- Utshwala be-Polyvinyl kukotini nendwangu ye-polyester ngemva kokuqeda ukuqina bukhulu, kodwa umuzwa unzima. Endwangu ye-polyester ayinwebekanga njenge-melamine resin, ukushesha kokugeza kungokwesibili ngemuva kwe-polyacrylate. Ukuqina kwendwangu yokuqeda isitashi kuhle, okwesibili kuphela ku-polyvinyl alcohol, kodwa ukusheshisa ukugeza kubi kakhulu.
- Indwangu ye-melamine resin yokuqeda i-polyester, umphumela wokuqina muhle uma kuqhathaniswa, futhi umuzwa owugqinsi nokunwebeka kungcono. Kodwa kumphumela wokuqeda ukotini awulungile, futhi ngemva kokuqeda indwangu izokhulula i-formaldehyde. I-Polyacrylate ukotini kumphumela oqinile wokuqeda ingcono, kumphumela wokuqeda indwangu ye-polyester ayilungile, kodwa ukushesha kokugeza kungcono kakhulu.
