Isingeniso Sezakhiwo ze-ABS Nezindlela Zokuguqula

I-ABS resin iyi-acrylonitrile-butadiene-styrene copolymer, njengenye yezinhlobo zepulasitiki ezisebenza kahle kakhulu, i-ABS ngakolunye uhlangothi, izinhlelo zokusebenza zemakethe ziyavuleka, ngakolunye uhlangothi, ngokuthuthukiswa kwezinhlobo ezintsha kanye nokuguqulwa kobuchwepheshe kanye nocwaningo lwe-alloy, iyaqhubeka iba eyesithupha ngobukhulu, ikakhulukazi ngokuguqulwa, i-ABS ithola izinhlobo ezintsha ezengeziwe. Ingaxutshwa nezinhlobonhlobo zama-resin ukuze yakhe ama-alloy, ngezinhlobo eziningi kanye nezinhlelo zokusebenza ezibanzi, futhi ingenye yepulasitiki yobunjiniyela eyinhloko.

Izakhiwo zomzimba ze-ABS

I-ABS iyi-resin ephuzi ekhanyayo noma enombala okhanyayo, ayinabo ubuthi, ayinambitheki, ayimuncwi amanzi amaningi, inezakhiwo ezinhle zomzimba nezomshini, njengezakhiwo zikagesi ezinhle kakhulu, ukumelana nokuguguleka, ukuzinza kobukhulu, ukumelana namakhemikhali kanye nokubukeka kokukhanya, kanye nokubumba okulula ukukucubungula. Inkinga ukumelana nesimo sezulu, ukumelana nokushisa okubi, kanye nokusha.

ABS plasticizakhiwo zemishini

I-ABS inezakhiwo ezinhle kakhulu zomshini, amandla ayo okushaya angcono kakhulu futhi ingasetshenziswa emazingeni okushisa aphansi kakhulu; I-ABS inokumelana okuhle kakhulu nokuguguleka, ukuzinza okuhle kobukhulu, kanye nokumelana namafutha, futhi ingasetshenziswa kuma-bearings ngaphansi komthwalo ophakathi kanye nesivinini. Izakhiwo zomshini ze-ABS zithinteka yizinga lokushisa.

Ububanzi bokusetshenziswa kwe-ABS

I-ABS ecwebezelayo ephezulu isetshenziselwa abahlanzi be-vacuum, abalandeli bakagesi, ama-air conditioner, ocingweni kanye neminye imikhiqizo yemishini yasekhaya, okufinyelelwa kuyo ngokulawula ubukhulu bezinhlayiya zerabha i-R+ (encane) ku-ABS. I-ABS ecwebezelayo ephansi isetshenziselwa amadeshibhodi, izembozo zezinsimbi, izinsika kanye nezinye izingxenye zangaphakathi zezimoto, ezigcwele ama-filler amakhulu ukuze zenze ukuncibilika okuncane ngaphandle futhi kunciphise ukucwebezela kwangaphandle.

Izinhlobo ze-ABS nezici

I-ABS engashisi (evimbela ilangabi) yezinga:

I-ABS iyinto evuthayo, ngokwencazelo ye-UL94 ingeyezinga le-HB. I-ABS icima ngokushesha uma ibamba umlilo, futhi ikhipha igesi enobuthi eningi kanye nentuthu emnyama, okungafanele ukusetshenziswa okungokoqobo. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nekhwalithi yokuphila, ukuqwashisa kwabantu ngokuphepha kuya ngokuya kuqina, ukusetshenziswa kwezimoto, ukwakhiwa, izinto zasendlini, nezinye izici zezinto zepulasitiki kubeka phambili izidingo eziqinile zokuvimbela umlilo, ukuthuthukiswa kwemininingwane nezindinganiso zobuchwepheshe ezihambisanayo, ngakho-ke lolu cwaningo lubaluleke kakhulu.
Izindlela ezintathu eziyinhloko zokunciphisa ukucinywa kwama-resin e-ABS:

1. Sebenzisa ama-polymer avimbela ilangabi ukuze uhlanganise ne-ABS, njenge-CPE, i-PVC;

2. Ukuguqulwa kwamakhemikhali kwe-ABS ekhona, njengokubamba iqhaza kwe-tribrominated styrene njenge-monomer yesine yokulungiselela i-ABS enezingxenye ezine;

3. Ngokusebenzisa indlela ejwayelekile ye-ABS yokubamba iqhaza, kufaka phakathi izinto ezivimbela ilangabi ezingaphili (njenge-MoO3) kanye nezinto ezivimbela ilangabi ezingaphili (njengezinto ezihlanganisiwe ze-halogen, izinto ezivimbela ilangabi ezingaphili). Uhlobo lwezinto ezivimbela ilangabi lunomphumela ophumelelayo wokuvimbela ilangabi, kodwa ezinye izakhiwo zingase zibe zimbi (njengokuguga, izindleko eziphezulu). I-ABS eguquliwe ngamakhemikhali idinga inqubo ethile yokusetshenziswa kanye nenqubo eyinkimbinkimbi kakhulu. Indlela yesithathu ithola ibhalansi phakathi kwezindleko nokusebenza futhi inozwela kakhulu ekwakhiweni kwezinto ezisebenza ngemisebenzi eminingi. Njengamanje, ukuguqulwa kwezinto ze-ABS ezivimbela ilangabi kusekelwe ekufakweni kwezinto ezivimbela ilangabi eziqukethe i-halogen ezisebenza kahle kakhulu.
