Kwindawo enkulu neyinkimbinkimbi yokucubungula i-polymer, apho oomatshini abaphambili badla ngokubamba ingqalelo, isihluzo serabha sisebenza njengomlindi ozolileyo nonganyanzelekanga womgangatho. Lo matshini uqinileyo nobonakala ulula udlala indima ebalulekileyo ekuqinisekiseni ubunyulu, ukuhambelana, kunye nokusebenza kwerabha edityanisiweyo, nto leyo eyenza ukuba ibe lilitye lesiseko lokwenziwa kweempahla zerabha ezithembekileyo.
Eyona nto iphambili kuyo, umsebenzi wesihluzo serabha, okanye isihluzo-ukukhupha, kukucoca. Umsebenzi wayo ophambili kukususa izinto ezingcolisayo—ezifana neziqwenga zesinyithi, iziqwenga zerabha ezinganyangekiyo, iifayibha zebhegi, okanye ezinye izinto zangaphandle—kwisixa serabha esidityanisiweyo ngaphambi kokuba senziwe amashiti, iipellets, okanye iimilo zokugqibela. Ukungeniswa kwezinto ezingcolisayo ezincinci kunokukhokelela ekusileleni okukhulu kwiimveliso ezigqityiweyo, okubangela amabala abuthathaka, ukuqhushumba kwamatayara, ukungasebenzi kakuhle kombane kwiintambo, okanye ukungafezeki kwizitywino zonyango. Ngoko ke, isihluzo sisebenza njengomgca wokugqibela wokhuselo kulawulo lomgangatho.
Uyilo lomatshini lunenjongo entle. Ngokwesiqhelo luquka ibhereli eqinileyo ye-extruder exhotyiswe ngesikrufu esinamandla. Irabha edityanisiweyo ifakwa kwibhereli, apho isikrufu siyenza iplastiki kwaye siyithumele ngamandla kwindawo ebalulekileyo: ipleyiti ye-breaker kunye ne-screen pack. I-screen pack, uthotho lwee-meshes zentsimbi ezinee-gauges ezincinci (ezihlala ziqala kwi-20 ukuya kwi-100 mesh), abaxubi be-lab kneader, yeyona nto iphambili kwinkqubo yokucoca. Njengoko irabha ecinezelweyo inyanzeliswa kwezi zikrini zincinci, ukungcola okuqinileyo kuyabanjwa. Irabha ehluziweyo emva koko idlula entloko ye-die ukuze yenze umtya oqhubekayo okanye iprofayili ethile, emva koko ipholiswa kwi-conveyor.
Izihluzo zerabha zanamhlanje zenzelwe ubunjineli obumangalisayo ukuze zikwazi ukumelana neemeko ezinzima. Zifanele ziphathe uxinzelelo oluphezulu, oludla ngokudlula iibhari ezingama-300, oluveliswa ngokunyanzela irabha ethambileyo kwizikrini ezincinci. Ukulawula oku, zinesakhiwo esomeleleyo esineebhareli eziqinisiweyo kunye neebheringi zokutyhala. Utshintsho oluphambili kukukwazi ukusebenza ngokuqhubekayo. Izihluzo zokuqala zazifuna ukuvalwa ukuze kucocwe isikrini ngesandla. Iimodeli zanamhlanje zisebenzisa iindlela zepiston ezimbini okanye i-slide-plate ezivumela ukuba i-screen pack itshintshiswe okanye icocwe ngaphandle kokuphazamisa ukuhamba, okunyusa kakhulu ukusebenza kakuhle kunye nokuhambelana.
Ukusetyenziswa kokuhluzwa kwerabha kuxhaphakile kulo lonke eli shishini. Kubalulekile ekwenzeni amatayara kwiikhompawundi zecala, i-tread, kunye ne-inner liner. Iimpahla zobugcisa ezisebenzayo kakhulu ezifana neepayipi, iibhanti, kunye nezinto zokudambisa zixhomekeke kwii-strainers ukuqinisekisa ukuqina kwesakhiwo. Mhlawumbi okona kubaluleke kakhulu, umenzi we-rubber roller, ukuhluzwa akunakuxoxiswana ngako ekuvelisweni kweemveliso zerabha zonyango, zokutya, kunye nezococeko, apho ubunyulu bubaluleke kakhulu.
Ngaphandle kokususa nje ungcoliseko, umatshini wokugquma irabha, isihluzo sikwanceda ekufaneni kwemveliso. Ukucheba okukhulu kunye noxinzelelo kwenza umxube werabha ube mnye, kuqinisekisa ukuba i-viscosity ihambelana ngakumbi kunye nokusasazeka kwezongezo. Oku kukhokelela ekuphuculweni kokusebenza kwimisebenzi efana nokufaka i-calendar okanye i-molding, imicu yokugquma i-silicone roller yoomatshini belaphu, ukunciphisa inkunkuma kunye nokuphucula iimpawu zemveliso yokugqibela.
Ukuqukumbela, isihluzo serabha singaphezulu kakhulu nje kwesihluzo esilula. Sisiqinisekiso esisisiseko sokhuseleko, ukuthembeka, kunye nomgangatho kwimveliso yerabha. Ukusebenza kwayo ngokungapheziyo phantsi kweemeko ezibuhlungu kuqinisekisa ukuba izixhobo eziphambili eziphuhliswe kwiilabhoratri ziguqulela kwiimveliso ezithembekileyo kwihlabathi lokwenyani. Nangona isenokungabi nabunzima bezixhobo ezithile ezisezantsi, indima yayo ayinakuthatyathelw’ indawo—iqhawe lokwenene elingadunyiswanga, elikhusela ngokuthe cwaka ukuthembeka kwezinto ezininzi zerabha ezenza umqolo wezothutho zanamhlanje, ishishini, kunye nobomi bemihla ngemihla.
