Inkqubo yokuvelisa irabha

Irabha yimathiriyeli enwebekayo edla ngokuthathwa kwilatex yemithi yerabha okanye imithombo yokwenziwa. Ibonisa ukuqina okugqwesileyo, ukuxhathisa kwe-abrasion, kunye nokumelana nokwaluphala, kuyenza isetyenziswe ngokubanzi kwizicelo ezahlukeneyo ezinje ngokwenziwa kwamatayara, itywina, imibhobho, iipads zerabha, nokunye. Inkqubo yemveliso yeemveliso zerabha isoloko ibandakanya amanyathelo aphambili aphambili okucutshungulwa okufana ne-mastication, i-compounding, i-calendering, i-extrusion, i-molding, kunye ne-vulcanization. Inyathelo ngalinye lidlala indima ebalulekileyo ekumiseleni ukusebenza kunye nomgangatho weemveliso zokugqibela. Ngezantsi inkcazo ecacileyo yenkqubo yokuvelisa iimveliso zerabha.

1. Ukuphulula:

Irabha ekrwada kunye nezongezo zixutywe kwaye zifudunyezwe kwi-rubber crusher ukuthambisa irabha, ukuphucula ukubambelela, kunye nokususa ukungcola okuqulethwe kuyo.

Imiba ephambili: Ukulawulwa kwexesha, ubushushu, amandla omatshini, kunye neentlobo / ubungakanani beearhente zokuthambisa.

2. Ukudibanisa:

Kwi-mixer, i-rubber kunye ne-additives ezahlukahlukeneyo (ezifana ne-vulcanization agents, i-anti-aging agents, fillers, njl.) zixutywe ngokulinganayo ukuze kuphuculwe ukusebenza kweemveliso zerabha.

Izinto eziPhambili: Uhlobo, umlinganiselo, kunye nokulandelelana kwezongezo, ukushisa okudibeneyo kunye nexesha, ukuxuba ubuninzi, phakathi kwabanye.

3. Ikhalenda:

I-rubber edibeneyo igxininiswe kumaphepha amancinci okanye amacwecwe amancinci ngumatshini we-calender ukwenzela ukucubungula okulandelayo kunye nokubumba.

Izinto eziphambili: Ukulawulwa kobushushu bekhalenda, isantya, uxinzelelo, ubulukhuni berabha, kunye ne-viscosity.

4. Extrusion:

I-rubber ikhutshwe ngumatshini wokukhupha ibe yimichilo eqhubekayo yezinto ezinobumba obuthile obunqamlekileyo, obusetyenziselwa ukuvelisa iimveliso zerabha kwiibhubhu, iintonga okanye ezinye iimilo ezinzima.

Izinto eziphambili: Ukulawulwa kobushushu bomatshini we-extrusion, uxinzelelo, isantya, uyilo lwentloko yokufa, njl.

5. Ukubumba:

Izinto zerabha zifakwe kwi-mold, kwaye phantsi kwesenzo sokufudumeza kunye noxinzelelo, igcwalisa i-mold cavity kwaye ifumene ifom efunwayo.

Izinto eziphambili: Uyilo lwe-Mold, ubushushu, uxinzelelo, ulawulo lwexesha, inani lokuzalisa irabha, kunye neempawu zokuhamba.

6. Ukwenziwa kweVulcanization:

Iimveliso zerabha ezibunjiweyo zibekwe kwisithando somlilo, kwaye ukusabela kwe-vulcanization kuqhutywa phantsi kobushushu obuthile, ixesha kunye noxinzelelo, ukuze iimolekyuli zerabha zidityaniswe, ngaloo ndlela ziphucule amandla omatshini, ukumelana nokunxiba kunye nokumelana nokuguga. irabha.

Imiba ephambili: Ukulawulwa kobushushu be-vulcanization, ixesha, uxinzelelo, uhlobo / ubungakanani bearhente etshabalalisayo, kunye nokuxinana kwekhonkco kunye nolwakhiwo.

Ingcaciso ethe kratya ngentla apha ichaza amanyathelo angundoqo okulungisa kwimveliso yeemveliso zerabha, kunye nokusebenza okufanelekileyo kwenyathelo ngalinye kunye nolawulo olubalulekileyo ekumiseleni umgangatho kunye nokusebenza kweemveliso zerabha zokugqibela.
