木飾(shi)面板生產過(guo)程中(zhong),口模唇出料不(bu)均(jun),制品產生質量缺陷的種類很多,馨如板面出現(xian)白帶、泡孔、板面薄(bo)厚不(bu)均(jun)、不(bu)結(jie)皮、豎向(xiang)液雅紋(wen)局部(bu)橫向(xiang)條紋(wen)、燕(yan)尾紋(wen)、凹坑、中(zhong)間鼓兩邊(bian)陷或(huo)兩邊(bian)陷中(zhong)間數、陰陽(yang)臉等。口模出料不(bu)均(jun)主要有以(yi)下原因:
6.使用(yong)未經(jing)活化的碳酸鈣或(huo)碳酸鈣粒(li)度過大,致(zhi)使混合(he)料分散不均,物料在擠出時流動速度紊(wen)亂。
7.配(pei)方中內外(wai)滑不(bu)平(ping)衡,致使分散不(bu)均或強(qiang)度差、易產生破(po)泡、流動速度過(guo)慢或過(guo)快,影響(xiang)塑化等(deng)。
由此可見,木(mu)飾面板生(sheng)(sheng)產過程中(zhong),口(kou)模唇出料不(bu)均對生(sheng)(sheng)產影響很大。木(mu)飾面板可以像木(mu)材一樣加工。小型(xing)木(mu)飾墻(qiang)面裝飾板機(ji)器變(bian)速

黃發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji)是放(fang)熱型發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji),發(fa)(fa)(fa)泡(pao)(pao)量大(da),發(fa)(fa)(fa)泡(pao)(pao)時間短(duan),發(fa)(fa)(fa)泡(pao)(pao)迅猛,突發(fa)(fa)(fa)性強。添(tian)加不(bu)適當,隨(sui)熔體(ti)(ti)黏度降低,會產生(sheng)過(guo)(guo)大(da)泡(pao)(pao)孔(kong)(kong)(kong),同(tong)樣(yang)會降低發(fa)(fa)(fa)泡(pao)(pao)率,并會產生(sheng)殘留物(wu)(wu)。除調節劑(ji)(ji)外(wai),還須添(tian)加白(bai)發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji)來平衡。白(bai)發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji)發(fa)(fa)(fa)泡(pao)(pao)率雖然不(bu)如黃發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji),發(fa)(fa)(fa)泡(pao)(pao)率低,但(dan)作為吸熱型發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji),發(fa)(fa)(fa)泡(pao)(pao)時間長,發(fa)(fa)(fa)泡(pao)(pao)平穩(wen),并能吸收黃發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji)發(fa)(fa)(fa)泡(pao)(pao)過(guo)(guo)程中所產生(sheng)的熱量,使前者冷卻,穩(wen)定和均衡釋(shi)放(fang)氣體(ti)(ti),提高自身發(fa)(fa)(fa)泡(pao)(pao)率,抑制厚板內部(bu)過(guo)(guo)熱降解,減少殘留物(wu)(wu);若白(bai)發(fa)(fa)(fa)泡(pao)(pao)劑(ji)(ji)添(tian)加少了(le),發(fa)(fa)(fa)泡(pao)(pao)體(ti)(ti)會不(bu)均勻,泡(pao)(pao)孔(kong)(kong)(kong)大(da)小不(bu)一,甚(shen)至(zhi)會出(chu)現比較大(da)氣孔(kong)(kong)(kong)和空穴,泡(pao)(pao)孔(kong)(kong)(kong)基本呈圓泡(pao)(pao)孔(kong)(kong)(kong)型。
若添加過(guo)量(liang),會(hui)使制品(pin)泡孔變粗,不(bu)細膩。
在不影響發(fa)泡(pao)(pao)率前提下,適當多添(tian)加吸熱型發(fa)泡(pao)(pao)劑(ji),取代部分黃發(fa)泡(pao)(pao)劑(ji),能抑制多添(tian)加發(fa)熱型發(fa)泡(pao)(pao)劑(ji)帶來的危害。河南木飾墻面裝(zhuang)飾板機器變速
