Silicone products show poo村作r appearance, is a very di跳還fficult job, common is to show dark不就 lines. What are the cau不能ses of dark lines in g書小eneral?


-, why do silicone products show 體玩dark marks


1, silica gel raw materials


Due to the different characteristics小她 of the original dat南錢a of silicone products, the product rat信厭io is different, so t那討he understanding of external 相歌adverse phenomena, the appearanc短技e of the elements is still based o腦妹n the distribution ra業照tio of the amount of海船 silica black and silicone 但請resin in the product, because th唱頻e original data is attributed to t腦湖he semi-transparent white solid ru通風bber, so in the mixing pro分歌cess, the mixing uniformity o也能f the rubber and vulcan見一ization agent depends on the筆多 quality of the rubber. And the 美弟elements of the poor appear國照ance of the product are 志河the above reasons!


2, silicone mold


The mold is the center of很農 silicone products, and the ma東花terial selection on the mold steel章船 occupies the primary element, 低熱followed by the poor appearance i和快n the processing process may be the def老多ormation phenomenon o高報f the mold with too many times of pres老坐sing, resulting in poor appe麗生arance of silicone products. Secon匠年dly, in the process of m章房old finishing, the accur民海acy of the mold selects the produ從司ct's closing line and self-removing熱是 edge and side wheel土河 Angle.


3, silicone products mo就厭lding vulcanization


Molding vulcan process, the prod線姐uct's exhaust method and trapp空書ed gas stroke select t拍醫he bulge phenomenon of si是愛licone products, time and te能說mperature distribution is not very l老拍ikely to lead to the app懂他earance of dark marks, in additio秒醫n to the most important is 就到the operation method of ma玩她chine personnel and whiteni和裡ng conditions, in the final ana飛資lysis, the most important th銀可ing in the processing p看務rocess is still to see the wind, si子快licone products should be su城麗itable for what kind of parameters equi船門pped and so on


Second, silicone products sh討還ow dark marks how to do


Silicone products have colorless,們睡 tasteless, endless characteristics, to拍費 change silicone produc兒窗ts into colorful colors, you nee請飛d to participate in the "col跳上or master", so the selec短照tion of color master mus章地t not show fault, assuming th美兵at the temperature of the color m水時aster is not, then basical工看ly silicone products have 外短become waste products, because the c數刀olor master should be integrated in就花to silicone products for high temper這不ature molding, At thi愛爸s time, the color sepa答件ration masterbatch is melted a知大t high temperature to make長計 the silicone product相爸s discolor, assuming that t聽銀he color masterbatch affects 讀知the entire production due 土厭to the temperature resistance function,費不 the result is clear and clea家鄉r, so the selection of the請自 color masterbatch must be selected th森美e most appropriate.


In the selection of silica gel 熱會data, it must be strict control, si很化lica gel data, such as two different si鄉厭licone data in the naked eye may be音答 difficult to difference col是老or difference and hardness,線答 but in fact, there are still diffe湖短rences between the two又話, if the two batches 什黃of silicone data mixed molding, then af舊間ter the molding quality風農 inspection found a small c化畫olor difference, it can not be ship著說ped. Our quality inspection is 聽車very serious, about the color differ照對ence can only be dealt with by 物東the method of defective products, s章風o, in the selection 快費of silica gel data mus區司t be clear without mixing, to know the 黑事source is very impor暗理tant, the head is wrong, the 了說whole process behind can onl照舊y be soy sauce.


The cutting process of silicone 煙老products should also be頻到 careful, because it is as制電sumed that the cutting rubber業讀 material is too thick o理弟r too narrow, it will b小金e more inconvenient in t鐵商he cutting of silicone products, an睡兵d it will also constitute the a鐵什ppearance of poor color af內秒ter the molding of sil學習icone products, even in the cutting p你近rocess, but also to ensure t日生he quality of the produc又土t.
