Dhalooyinka dhalooyinka waxay noqdeen qayb muhiim ah oo ka mid ah warshadaha dawooyinka

Muraayadaha sida silicate walxo aan dabiici ahayn, waxqabad yara deggan, iyo hufnaan siman, gaar ahaan ku habboon baakadaha iyo kaydinta daawooyinka. Isla mar ahaantaana, marka loo eego alaabta kale, qiimaha galaasku waa mid raqiis ah. Sanadihii la soo dhaafay, iyada oo horumarinta degdega ah ee warshadaha dawooyinka, warshadaha muraayadaha dawooyinka ee dalkeena iyo badeecada la helay horumarka degdega ah iyo hagaajinta, waxay noqotay alaabta baakadaha ugu weyn ee berrinkii baakadaha dawooyinka, alaabta baakadaha muraayadda ayaa si ballaaran loo isticmaalaa duritaanka. duritaanka budada, lyophilizer-ka, alaabta noolaha, alaabta dhiiga, dareeraha afka, alaabta daryeelka caafimaadka, sida dhalooyinka dhalada ah ayaa si weyn loogu isticmaalaa noocyada kala duwan ee baakadaha daawada

Buugaagta tignoolajiyada baakadaha dhalada ee Shiinaha ayaa noqon doona noocyo kala duwan oo galaas ah oo loo qaybiyay 11 qaybood, marka loo eego habka wax soo saarka ee injineernimada waxaa iska leh dhalada dhalada, laakiin marka loo eego waxqabadkeeda iyo isticmaalkeeda waa inay ka tirsan yihiin galaaska qalabka. Dhalada dhalada ah waa weel dhaqameed oo cabitaanka lagu shubo gudaha Shiinaha, dhalada sidoo kale waa baakad taariikhi ah. Iyada oo ay ku soo qulqulayaan noocyo badan oo ah alaabada baakadaha ee suuqa, weelka dhalada ayaa wali ku jira boos muhiim ah oo ku jira baakadaha cabitaanka, taas oo aan ka soocnayn sifooyinkeeda baakadaha oo aan lagu beddeli karin agab kale oo baakadaha. Maaddaama ay daawadu tahay shay gaar ah, dhammaan noocyada kala duwan ee alaabooyinka muraayadaha daawada loo isticmaalo sida weelasha baakaddeedu waxay leeyihiin halbeeg kiimiko oo ka fiican, waxqabad iyo shuruudo tayo leh marka loo eego dhalooyinka caadiga ah. Weelka dhalooyinka borosilicate ee hooseeya ayaa had iyo jeer ahaa baakadaha ugu weyn ee cirbadeynta Shiinaha. Si kastaba ha ahaatee, buuxinta aashitada iyo dareeraha alkali ee weelka galaaska borosilicate hoose oo leh heerka caabbinta biyaha hoose waa sahlan tahay in ay u horseeddo jirro shisheeye oo muuqda sida qolof iyo dhibco caddaan ah muddada waxtarka leh. Sida qayb muhiim ah oo ka mid ah daawada, alaabta baakadaha dawooyinka ayaa si dhow ula xidhiidha horumarinta warshadaha dawooyinka.

Dabeecadda culus iyo jilicsanaanta dhalooyinka ayaa horseeday iska caabin baahsan oo suuqa ah oo ka dhan ah dhalooyinka muraayadaha daawada ah. Laakiin sannadihii la soo dhaafay, balaastiigga (qaabka: resin synthetic, plasticizer, stabilizer, pigment) dhalooyinka AA phenol, caag caag ah, dhalooyinka muraayadaha daawada ee dib u soo celinta booska suuqa, muraayadda daawada waxay leedahay faa'iidooyinka tartanka soo socda: waxay leedahay xasilloonida kiimikada wanaagsan. , ma aha sababtoo ah kor u kaca heerkulka, sii deynta walxaha sunta ah, iyo wasakhowga gudaha dhalada oo labisan; Dhalooyinka dhalada ah ee adkaanta sare, ma aha sababtoo ah qallafsanaanta extrusion, haddii kale weelku kama ilaalin karo extrusion; Isticmaalka dhalooyinka dhalada ah ee ay ku jiraan daroogooyinka, macaamiishu waa la hubaa, dhalooyinka galaaska kumanaan sano oo taariikh ah, ammaankeeda ayaa si weyn loo aqoonsaday, alaabooyinka ku jira waa ka badbaado badan yihiin, waana sahlan tahay in la jeermiyo; Qaabku wuxuu noqon karaa mid isbedeli kara, fududahay in la qurxiyo, alaabta dharka ayaa muujinaya heer sare, kor u qaadista iibka.
