Assor ac: saamaynta adkaysata, heerkulka sare u adkaysata, bey'ada bay u fiican tahay

Waa maxay waxyaabaha maqnaanaya? Calaamadda ABR waa mid tilmaanta ah oo ka kooban saddex momomers, acrylonitrile (a), Budadiene (b), iyo styrene (yada). Nuxurka qaraabada ah waa loo beddeli karaa si aan waxtar lahayn si loo sameeyo waxoogaa kala duwan. Inta badan ab ka mid ah balaastikada way adagtahay in laga falceliyo walxaha kale ee heerkulka qolka sababta oo ah xasilloonidooda, si aysan u lahayn saameyn toos ah oo ku saabsan noolaha.

1. Absal Resin waa mid ka mid ah shanta weelka isku-darka ee ugu weyn. Waxay leedahay iska caabbinta saamaynta, iska caabbi kuleylka, iska caabbinta heerkulka, iska caabbinta kiimikada, guryaha korantada wanaagsan, ka baaraandegista sahlan, cabirrada sheyga ee xasilloon, iyo furaha dusha sare ee dusha sare, iyo furaha dusha sare. Way fududahay in la rinjiyeeyo iyo midabka, waxaana sidoo kale loo isticmaali karaa buufinta dusha sare, elektaroonigga ah, iyo balantaroolka injineerrada ee themormoplastic. Acrylonitrile-Budienene-Styrene waa acrylonitrile, Budienene iyo Styrene. Ingiriisiga, waxaa loo yaqaan Acrylonitrile-Butalene- Styrene copolymer, ama Ajka oo gaaban. Axdu badanaa waa midab huruud huruud ah ama caano jilicsan oo caano ah. ABS waa mid ka mid ah balaastigga injineernimada inta badan la isticmaalo.

2. Cayayaanka maqalka ah waa kuwa ugu weyn oo aadka loo isticmaalo polymer ee ugu badan ee loo yaqaan adduunka. Waxay si dabiici ah isugu dari kartaa sifooyinka kala duwan ee PB, digsiga iyo PS, waxayna leedahay guryo farsamo oo heer sare ah oo adag, adag iyo isku-dheelitirka adag. ABS waa acrylonile of acrylonitrile, Budadine iyo Stryrene, A waa Acrylonitrile, B waa Butadiene, iyo s waa styrene. Isticmaalka dhabta ah ka dib, waxaa la ogaadaa in: Maqnaanshaha tuubooyinka caagga ah uma adkeysan karaan xarkaha acid ee sulfuric, waxaana lagu jebin doonaa marka ay ku dhacdo aashitada sulfuric.

Sababtoo ah Abs Resin wuxuu leeyahay seddex qaybood, waxay leedahay wax qabad wanaagsan; Acrylonitrile waxay siisaa maqnaane xasillooni kiimiko, iska caabbinta saliida, adkaanta qaarkood iyo adkaanta; Budadiene si weyn waxay si weyn u wanaajisaa adkaanta, saamaynta iyo iska caabinta qabow ee maqnaanshaha Absin; Styrene waxay leedahay guryo dabiici ah oo wanaagsan iyo wax-qabadka.

Inta badan abs waa kuwa aan sun ahayn oo aan loo isticmaali karin biyaha, laakiin waxyar ayaa loo dafiri karaa uumiga biyaha, oo leh heerka biyo yaraanta biyaha yar. Dusha sare ee ashyaa'da alaabada dib-u-celinta ah waa la nadiifin karaa si loo helo alaabooyin sareeya oo sareeya.

ABS waxay leedahay guryo dhameystiran oo jireed iyo farsamo yaqaan ah, iyo sidoo kale iska caabin saac ah oo heer degmo oo wanaagsan. Cabbirka xasilloonida korantada korantada, xidhashada, iska caabbinta kiimikada, iska caabbinta jiirka, iska caabbinta jiifka, wax soosaarka la dhammeeyay iyo wax soo saarka wax soo saarka iyo ka shaqeynta farsamada. Abs Resin waa u adkaysaa biyaha, cusbada inorganic, aashitada, insulanta, insiossios, interos-ka, waxaa si fudud loogu milmiyaa aldenehydes, kelones, esters iyo qaar ka mid ah hydrocarbons-ka. Abs Resin wuxuu leeyahay heerkulka degdegga kuleylka kuleylka hooseeya iyo iska caabin cimilo oo sabool ah. Barta dhalaalaysa waa 217 ~ 237 ℃, heerkulka jabinta kuleylka kuleylka ayaa ka sarreeya 250 ℃. Waqtigan xaadirka ah, inta badan wax ka badalida maqaarka aaladda suuqa waa qalabka birta iyo alaabada dib loo warshadeeyo. Waxqabadka badeecadaha loo yaqaan 'Macaamiisha' ee macaamiisha loo soo bandhigo ma xasilloon tahay.

Ballaarinta; Asse abs waa mid aad u adag, sidaa darteed waxay leedahay iska caabin adag, xoqida xoqida, iska caabbinta cabbirka, xasilloonida cabbirka iyo guryaha kale.

Asse abs sidoo kale waxay leedahay iftiin wanaagsan. Marka la barbar dhigo acrylic isku mid ah daahfurnaanta, in kasta oo ay leedahay adag, qiimaha uu aad u sarreeya, midabkuna uma badna sida acrylic, guud ahaan maadaama beige, madow iyo hufan. .

Caantu sidoo kale waa mid aad u fiican deegaanka. Sababo la xiriira isticmaalka kiimikada deegaanka u wanaagsan ee bey'adda, waa mid aan sun lahayn iyo ur la'aan, oo sidoo kale waxaa laga yaabaa in lagu xakameeyo korantada. Waa qalab aad u nabdoon.

Asse abs-ka waa sahlan tahay in la habeeyo jawiga heerkulka sare, heerkulka cilfashinta ah waa 93-118 ℃, laakiin waxay si fiican u fulisaa jawiga heerkulka hooseeya, marka sidoo kale waa shey heerkul u adkaysata.

Shirkaddeenu waxay si qoto dheer ugu mashquulsan tahay balaastigga injineerinka waxqabadka sare, waxaana ka go'an inay siiso xalka maaddada hal-abuurka ah ee warshadaha soo-saarka ee ugu sareeya. Alaabooyinkayaga ugu muhiimsan waxaa ka mid ah go'yaal caag ah oo dhameystiran sida poloyoxymymerene (pom), polycharbonate (polychertonenenene (polyphertones), iwm), polyphertones (polythertone), phenole-ka (phenethertone) iyo gudiga galaaska galaaska ephox. Iyada oo leh guryo aad u wanaagsan sida caabbinta heerkulka sare, iska caabbinta, iyo xoog sare, alaabooyinkeena ayaa si weyn loogu adeegsadaa gawaarida tamarta cusub, mashiinka elektaroonigga ah, mashiinnada warshadaha, aerospace iyo beero kale.
