Kusimbisa machira chinhu chinoshandiswa ne organic polymer chinovandudza chitarisiko chejira, chinowedzera kusimba uye huremu hwejira, uye chinoita kuti rinzwe rakasimba. Chinhu chakakosha pakubatsira kupedzisa. Jira rakagadziriswa rinogona kushandiswa zvakanyanya mumachira ekushongedza, kunyanya machira emaketeni, machira emabhegi uye machira akarukwa. Rinoshandiswawo mukugadzira interlining (fusible interlining uye resin interlining).
Munyika dzekumadokero dzakasimukira, emulsion polyacrylate makomisheni nekuda kwemutengo wakaderera, nyore synthesis, yakagadzikana kuita uye zvimwe zvakanakira muindasitiri yekudhinda machira nekudhaya yakashandiswa zvakanyanya. Inonyanya kushandiswa stiffener ndeiyi: melamine resin, urea-formaldehyde resin, polyacrylate, polyvinyl acetate, polyvinyl doro uye starch, uye zvigadzirwa zvavo zvakagadziridzwa.
Zvakanakira uye kuipa kwevakasimba
zita | Advantages | payakaipira |
Melamine resin | Mushure mekupedza kuoma kwejira, shrinkage, elasticity, kunzwa zviri nani, kunyanya kune synthetic fiber stiffness effect yakanaka. | Mushure mekupedza, jira riri nyore kutora unyoro, kuoma uye kuomarara kuderera, kutsvuka uye kuderera kwesimba, kuburitswa kwemahara formaldehyde, nezvimwewo. |
Urea-formaldehyde resin | Mushure mekupedza, jira rine kuomarara kuri nani uye yakaderera mutengo wezvinhu. | Mushure mekupedza, jira racho rine hurombo husina kunaka, rough handfeel, shrinkage yakakura, kushomeka kwekugeza kwekudzivirira uye kusunungurwa kwemahara formaldehyde. Kusagadzikana kwekuchengetedza kugadzikana kweanopedzisa agent. |
Polyacrylates uye polyvinyl acetates | Iine maitiro ekudzivirira chiedza, kuchembera kuramba uye hakuna yellowing. Nyore kugadzira, yakanaka kuchengetedza kugadzikana, haiburitse yemahara formaldehyde. Kuomesa mhedzisiro yakanaka, kunyanya kune cellulose fiber jira rinoomesa kupedzisa. | Huwandu hwakafanana hwekupedzisa mumiriri, iyo kuomesera machira ekugadzira machira yakaderera kune melamine resin. Mushure mekupedza, jira rinoshaya elasticity uye kunzwa kwakakora. Polyvinyl acetate ine brittle uye ine kushomeka kwechando. |
Polyvinyl doro | Iine rheology yakanaka uye inogona kuumba firimu rine simba guru, iro rine maitiro akanaka ekuomesa pamucheka we cellulose. | Zvakaoma kusvibisa pasi pezvakatipoteredza uye zvinogona kuumba huwandu hwakawanda hwefuro mumvura. Kupedzisa mumiriri mumucheka mushure mekupisa kuri nyore kupfava uye kubuda ropa, kushambidzika kwakashata. |
Yakagadziriswa starch | Zviri nyore kuwana mbishi, mutengo wakaderera, usingaore, nyore kushandisa, biodegradable, uye unogona kuita kuti jira rive nekuomarara. | Mushure mekupedza, kuoma kwejira kunoderera nekunyorova, uye zviri nyore kuparara uye kuva moldy. Kusagona kugeza zvakanaka, kushata kwemaoko, uye kusasimba. |
Gadzirisa mapoinzi akakosha
Nzira yekugocha ine simba guru pane formaldehyde pamucheka wejira uye kuoma kwejira mushure mekupedza. Nekuwedzera kwekupisa nguva uye kupisa kwekushisa, kuoma kunowedzera uye zvinyorwa zve formaldehyde pamucheka wejira zvinoderera zvakanyanya. Kana iyo nzira yekugadzirisa ichidzorwa pa200 ° C × 60s, iyo formaldehyde pamucheka inogona kusvika pazasi 75ppm.
Izvi zvinodaro nekuti nekusimudzirwa kwekuomeswa, kuyambuka kweiyo stiffener kunowedzera kukwana, saka kuoma kwejira mushure mekupedza kunowedzera. Kune rumwe rutivi, iyo formaldehyde pamucheka wekupedzisa iri nyore kuvhuvhuta pasi pemamiriro ekushisa kwepamusoro, zvichiita kuti pave ne formaldehyde yakaderera pamucheka wekupedzisira.
Pane kuenzana kunodzoserwa pakati pechinhu chinosimbisa uye formaldehyde. Nekuchinja kwenzvimbo yekunze (yakadai se: tembiricha, hunyoro, pH, nezvimwewo), formaldehyde inoparadzaniswa nguva dzose. Mushure mekupedzwa kwemuenzaniso wekutanga wejira, formaldehyde inoderera, nekuwedzerwa kwenguva yekuchengetedza formaldehyde inowedzera zvishoma nezvishoma. Kana nguva yekuchengetedza yasvika mazuva gumi kusvika gumi nemaviri, formaldehyde inosimbiswa zvakanyanya.
Kana yakachengetwa munzvimbo isina mhepo, iyo formaldehyde yakaburitswa ichaunganidza zvakanyanya, pachava nekunzwa kunorwadza uye hutsinye. Zvinokurudzirwa kuti jira mushure mekupedza nekuoma resin inofanira kuchengetwa munzvimbo ine mhepo yakanaka.
Inoshanda mamiriro ega ega ega estiffener
- Mucheka wedonje mushure mekupedza kuoma: polyvinyl doro> polyacrylate> starch> melamine resin.
- Polyester jira mushure mekupedza kuoma: polyvinyl doro> starch> melamine resin> polyacrylate.
- Kugeza kukurumidza: polyacrylate> polyvinyl doro> melamine resin> starch.
- Polyvinyl doro mukotoni uye machira epolyester mushure mekupedza kuomarara kwakakura, asi manzwiro acho akanyanya. Mumucheka wepolyester hauna elastic se melamine resin, kukurumidza kugeza ndeyechipiri kune polyacrylate. Starch kupedzisa jira kuoma kwakanaka, yechipiri chete kune polyvinyl doro, asi kukurumidza kugeza kwakashata.
- Melamine resin inopedzisa polyester jira, kuomarara mhedzisiro yakanaka, uye kunzwa gobvu uye elasticity zviri nani. Asi mukotoni yekupedzisa mhedzisiro haina kunaka, uye mushure mekupedza jira richaburitsa formaldehyde. Polyacrylate mukotoni pane yakaoma yekupedzisa mhedzisiro iri nani, mu polyester machira ekupedzisa mhedzisiro haina kunaka, asi kukurumidza kugeza ndiyo yakanyanya kunaka.
