1.橡膠制品的主要原料是以生膠為基本材料，而生膠就是生長(zhǎng)在熱帶，亞熱帶的橡膠樹上通過(guò)人工割開樹皮收集而來(lái)。 2.各種配合劑，是為了改善橡膠制品的某些性能而加入的輔助材料。 3.纖維材料有(棉、麻、毛及各種人造纖維、合成纖維和金屬材料、鋼絲)是作為橡膠制品的骨架材料，以增強(qiáng)機(jī)械強(qiáng)度、限制制品變型。在原材料準(zhǔn)備過(guò)程中配料必須按照配方稱量準(zhǔn)確。為了使生膠和配合劑能相互均勻混合，需要對(duì)材料進(jìn)行加工，上海質(zhì)量衛(wèi)生潔具用橡膠產(chǎn)品哪家好。生膠要在60--70℃烘房?jī)?nèi)烘軟后再切膠、破膠成小塊，配合劑有塊狀的。如石蠟、硬脂酸，上海質(zhì)量衛(wèi)生潔具用橡膠產(chǎn)品哪家好、松香等要粉碎，上海質(zhì)量衛(wèi)生潔具用橡膠產(chǎn)品哪家好。粉狀的若含有機(jī)械雜質(zhì)或粗粒時(shí)需要篩選除去液態(tài)的如松焦油、古馬隆需要加熱、熔化、蒸發(fā)水分、過(guò)濾雜質(zhì), 配合劑要進(jìn)行干燥不然容易結(jié)塊、混煉時(shí)若不能分散均勻硫化時(shí)產(chǎn)生氣泡會(huì)影響產(chǎn)品質(zhì)量。上海質(zhì)量衛(wèi)生潔具用橡膠產(chǎn)品哪家好</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">1.橡膠制品成型時(shí)，經(jīng)過(guò)大壓力壓制，其因彈性體所俱備之內(nèi)聚力無(wú)法消除，在成型離模時(shí)，往往產(chǎn)生極不穩(wěn)定的收縮(橡膠的收縮率，因膠種不同而有差異) ，必需經(jīng)過(guò)一段時(shí)間后，才能和緩穩(wěn)定。所以，當(dāng)一橡膠制品設(shè)計(jì)之初，不論配方或模具，都需謹(jǐn)慎計(jì)算配合，若否，則容易產(chǎn)生制品尺寸不穩(wěn)定，造成制品品質(zhì)低落。 2.橡膠屬熱溶熱固性之彈性體，塑料則屬于熱溶冷固性。橡膠因硫化物種類主體不同，其成型固化的溫度范圍，亦有相當(dāng)?shù)牟罹?，甚至可因氣候改變，室?nèi)溫濕度所影響。因此橡膠制成品的生產(chǎn)條件，需隨時(shí)做適度的調(diào)整，若無(wú)，則可能產(chǎn)生制品品質(zhì)的差異。上海質(zhì)量衛(wèi)生潔具用橡膠產(chǎn)品規(guī)格尺寸</p><div

style="text-indent:25px">3.橡膠產(chǎn)品是由橡膠原料進(jìn)行密煉機(jī)煉膠后制成的混煉膠作原材料，在煉膠時(shí)根據(jù)所需橡膠制品的特性而設(shè)計(jì)配方，并且定下所需要的產(chǎn)品硬度。產(chǎn)品制作成型由橡膠平板硫化機(jī)進(jìn)行模壓成型。產(chǎn)品成型后***進(jìn)行飛邊處理，把產(chǎn)品表面處理光滑無(wú)毛刺。 4.橡膠制品老化測(cè)試屬于老化測(cè)試范疇，橡膠老化是指橡膠及制品在加工，儲(chǔ)存和使用過(guò)程中，由于受到內(nèi)外因素的綜合作用引起性能結(jié)構(gòu)發(fā)生改變，進(jìn)而喪失使用價(jià)值的現(xiàn)象。表現(xiàn)為龜裂，發(fā)粘，硬化，軟化，粉化，變色，長(zhǎng)霉等。 </p><p style="text-indent:25px">三、塑煉生膠富有彈性,缺乏加工時(shí)必需的可塑性性能,因此不便于加工。為了提高其可塑性,所以要對(duì)生膠進(jìn)行塑煉,這樣在混煉時(shí)配合劑就容易均勻分散在生膠中,同時(shí)在壓延、成型過(guò)程中也有助于提高膠料的滲透性滲入纖維織品內(nèi)和成型流動(dòng)性。將生膠的長(zhǎng)鏈分子降解形成可塑性的過(guò)程叫做塑煉。生膠塑煉的方法有機(jī)械塑煉和熱塑煉兩種。機(jī)械塑煉是在不太高的溫度下通過(guò)塑煉機(jī)的機(jī)械擠壓和摩擦力的作用使長(zhǎng)鏈橡膠分子降解變短由高彈性狀態(tài)轉(zhuǎn)變?yōu)榭伤軤顟B(tài)。熱塑煉是向生膠中通入灼熱的壓縮空氣在熱和氧的作用下使長(zhǎng)鏈分子降解變短從而獲得可塑性。 </p><p style="text-indent:25px">四、混煉為了適應(yīng)各種不同的使用條件、獲得各種不同的性能,也為了提高橡膠制品的性能和降低成本必須在生膠中加入不同的配合劑。混煉就是將塑煉后的生膠與配合劑混合、放在煉膠機(jī)中通過(guò)機(jī)械拌合作用使配合劑完全、均勻地分散在生膠中的一種過(guò)程。混煉是橡膠制品生產(chǎn)過(guò)程中的一道重要工序,如果混合不均勻就不能充分發(fā)揮橡膠和配合劑的作用影響產(chǎn)品的使用性能?；鞜捄蟮玫降哪z料人們稱為混煉膠它是制造各種橡膠制品的半成品材料,俗稱膠料通常均作為商品出售購(gòu)買者可利用膠料直接加工成型、硫化制成所需要的橡膠制品。根據(jù)配方的不同?混煉膠有一系列性能各異的不同牌號(hào)和品種?提供選擇。上海質(zhì)量衛(wèi)生潔具用橡膠產(chǎn)品哪家好</p><p
