水性木器漆有許(xu)多(duo)品(pin)種,按成膜物(wu)質的(de)(de)(de)種類(lei)(lei)分(fen)(fen)(fen)(fen),可分(fen)(fen)(fen)(fen)為(wei)(wei):單(dan)組(zu)(zu)(zu)分(fen)(fen)(fen)(fen)聚(ju)氨(an)酯(zhi)分(fen)(fen)(fen)(fen)散體、丙(bing)(bing)烯(xi)(xi)酸乳液、雙(shuang)組(zu)(zu)(zu)分(fen)(fen)(fen)(fen)水性(xing)(xing)聚(ju)氨(an)酯(zhi)等(deng)(deng),不(bu)同的(de)(de)(de)成膜物(wu)質從根本上決定(ding)了(le)(le)其(qi)性(xing)(xing)能,單(dan)組(zu)(zu)(zu)分(fen)(fen)(fen)(fen)聚(ju)氨(an)酯(zhi)分(fen)(fen)(fen)(fen)散體有良好的(de)(de)(de)硬(ying)度(du)、柔韌(ren)性(xing)(xing)、耐(nai)(nai)(nai)磨(mo)性(xing)(xing)、抗粘結性(xing)(xing)、豐(feng)滿(man)度(du)等(deng)(deng);雙(shuang)組(zu)(zu)(zu)分(fen)(fen)(fen)(fen)聚(ju)氨(an)酯(zhi)則進一(yi)(yi)步(bu)提高(gao)了(le)(le)耐(nai)(nai)(nai)化學(xue)品(pin)性(xing)(xing)能;丙(bing)(bing)烯(xi)(xi)酸乳液的(de)(de)(de)耐(nai)(nai)(nai)候(hou)性(xing)(xing)及(ji)耐(nai)(nai)(nai)光性(xing)(xing)突出。按應(ying)用場合(he)(he)可分(fen)(fen)(fen)(fen)為(wei)(wei):地板(ban)漆(qi)、家具(ju)漆(qi)、裝(zhuang)飾(shi)裝(zhuang)修(xiu)漆(qi) ( 門(men)、窗套,護(hu)墻板(ban) ) 等(deng)(deng),地板(ban)漆(qi)要求(qiu)(qiu)漆(qi)膜的(de)(de)(de)耐(nai)(nai)(nai)磨(mo)性(xing)(xing)、韌(ren)性(xing)(xing)、硬(ying)度(du)、耐(nai)(nai)(nai)化學(xue)品(pin)等(deng)(deng)性(xing)(xing)能好,家具(ju)漆(qi)及(ji)裝(zhuang)飾(shi)裝(zhuang)修(xiu)漆(qi)偏重于裝(zhuang)飾(shi)性(xing)(xing)。究(jiu)竟(jing)按哪一(yi)(yi)種分(fen)(fen)(fen)(fen)類(lei)(lei)較(jiao)為(wei)(wei)合(he)(he)適(shi),上述(shu)國外(wai)標(biao)(biao)準中(zhong)(zhong), IOS — MAT- 0024 、 EN 927 — 1 : 1996 、 ENV 927 — 2 : 2000 按木器漆(qi)的(de)(de)(de)應(ying)用場合(he)(he)進行分(fen)(fen)(fen)(fen)類(lei)(lei), ASTM D 2571 - 95 、 ASTM 2336--99 中(zhong)(zhong)則明確規定(ding)標(biao)(biao)準所屬木器漆(qi)的(de)(de)(de)用途,因此按應(ying)用場合(he)(he)分(fen)(fen)(fen)(fen)類(lei)(lei)體現最終性(xing)(xing)能要求(qiu)(qiu),而無(wu)須考慮是聚(ju)氨(an)酯(zhi)類(lei)(lei)還是丙(bing)(bing)烯(xi)(xi)酸類(lei)(lei)較(jiao)為(wei)(wei)合(he)(he)適(shi)。
水性木器漆廠家講述水性木(mu)器漆應該(gai)具備(bei)哪些性能(neng) ?
狀態:
涉(she)及了(le)結皮、分層、沉淀等(deng)現象,體(ti)現了(le)水性(xing)木器漆的開罐效應,試驗方法參考 GB / T 9756--2001 。
粘度:
粘度(du)(du)(du)是水(shui)性木器漆(qi)較(jiao)重要(yao)的性能指標。應根據(ju)水(shui)性木器漆(qi)的種類(lei),如清(qing)漆(qi)、清(qing)啞(ya)(ya)光、白色漆(qi)等分別作(zuo)出(chu)要(yao)求。若清(qing)啞(ya)(ya)光漆(qi)粘度(du)(du)(du)太小,啞(ya)(ya)光粉(fen)容易沉淀,甚至形成(cheng)硬沉底,施(shi)工時不易攪勻,涂刷出(chu)的漆(qi)膜光澤會均勻不一(yi),影(ying)響效果。有(you)光清(qing)漆(qi)的粘度(du)(du)(du)恰當,無需或兌稀很(hen)少,可提(ti)高一(yi)道刷涂厚度(du)(du)(du),提(ti)高豐滿度(du)(du)(du)。檢(jian)驗(yan)方法有(you) GB / T l723 — 1993 中(zhong)(zhong)涂- 4 杯法或 GB / T2794 — 1993 中(zhong)(zhong)旋轉粘度(du)(du)(du)計(ji)法。
應(ying)根據(ju)分類,選擇其中部分性(xing)(xing)(xing)(xing)(xing)能項目(mu)作為該(gai)類水性(xing)(xing)(xing)(xing)(xing)木(mu)器漆(qi)(qi)的性(xing)(xing)(xing)(xing)(xing)能要求(qiu)。水性(xing)(xing)(xing)(xing)(xing)木(mu)器漆(qi)(qi)最(zui)大優(you)勢(shi)在于其環保性(xing)(xing)(xing)(xing)(xing),因此(ci)無論哪一(yi)類都應(ying)該(gai)著重突出揮發性(xing)(xing)(xing)(xing)(xing)有機化(hua)(hua)合(he)物總量這一(yi)項性(xing)(xing)(xing)(xing)(xing)能要求(qiu),而其它性(xing)(xing)(xing)(xing)(xing)能,如硬度(du)、耐(nai)磨性(xing)(xing)(xing)(xing)(xing)、耐(nai)化(hua)(hua)學(xue)介(jie)質性(xing)(xing)(xing)(xing)(xing)應(ying)考(kao)(kao)慮(lv)到水性(xing)(xing)(xing)(xing)(xing)化(hua)(hua)后固有的弊病和實際應(ying)用(yong)場合(he)所(suo)需的性(xing)(xing)(xing)(xing)(xing)能,不應(ying)按照溶劑型漆(qi)(qi)生搬(ban)硬套。地(di)板漆(qi)(qi)應(ying)全面考(kao)(kao)察(cha)漆(qi)(qi)膜的性(xing)(xing)(xing)(xing)(xing)能,家(jia)具漆(qi)(qi)則重點考(kao)(kao)察(cha)耐(nai)磨性(xing)(xing)(xing)(xing)(xing)、柔韌性(xing)(xing)(xing)(xing)(xing)、硬度(du)、耐(nai)化(hua)(hua)學(xue)品(pin)性(xing)(xing)(xing)(xing)(xing)等性(xing)(xing)(xing)(xing)(xing)能,而裝飾(shi)裝修漆(qi)(qi)則適當考(kao)(kao)慮(lv)硬度(du)、耐(nai)化(hua)(hua)學(xue)品(pin)性(xing)(xing)(xing)(xing)(xing)等性(xing)(xing)(xing)(xing)(xing)能。
