Makampani opanga mphira amaphatikiza mawu aukadaulo osiyanasiyana, omwe mwatsopano latex amatanthawuza mafuta oyera odulidwa kuchokera kumitengo ya rabala.
Labala yokhazikika imagawidwa kukhala 5, 10, 20, ndi 50 tinthu mphira, pomwe SCR5 imaphatikizapo mitundu iwiri: mphira wa emulsion ndi mphira wa gel.
Zomatira zokhazikika zamkaka zimapangidwa ndi kulimba, granulating, ndi kuyanika latex, pomwe zomatira zokhazikika zimapangidwa ndi kukanikiza, granulating, ndi kuyanika filimu yowuma ya mpweya.
Kukhuthala kwa Mooney ndi chizindikiro choyezera makokedwe ofunikira kuti kasinthasintha kazungulira mu nkhungu ya rabara pamikhalidwe inayake.
Themphira wouma Zomwe zili mkati zimatanthawuza magilamu omwe amapezeka mwa kuyanika 100g ya latex pambuyo pa kulimba kwa asidi.
Rubber wagawidwa kukhalamphira yaiwisi ndimphira wovunda, yoyamba inali ya mphira yaiwisi ndipo yomalizirayo inali ya mphira yopingasa.
Wophatikiza wothandizira ndi mankhwala omwe amawonjezedwa ku rabara yaiwisi kuti apititse patsogolo magwiridwe antchito a mphira.
Mpira wopangira ndi polima zotanuka kwambiri zopangidwa ndi polymerizing monomers.
Labala wobwezerezedwanso ndi zinthu zopangidwa kuchokera ku zinyalala za rabara zotayidwa ndi zinyalala za labala zowombedwa.
Vulcanizing agents zingayambitse mphira wolumikizana, pomwekuyaka ndiko kuchitika msanga kwa vulcanization phenomenon.
Othandizira ndifillers motero kusintha mawonekedwe a raba ndikuchepetsa mtengo.
Zofewa or plasticizers kuwonjezera mphira plasticity, pamenekukalamba kwa rabara ndi njira ya pang'onopang'ono kutaya katundu mphira.
Antioxidants kuchedwetsa kapena kuletsa kukalamba kwa mphira ndipo amagawidwa kukhala mankhwala ndi odana ndi kukalamba.
Frost kupopera mbewu mankhwalawa ndikupopera sulfure kutanthauza chodabwitsa cha sulfure ndi zina zowonjezera kupopera mbewu mankhwalawa ndi sulfure precipitating ndi crystallizing, motero.
Pulasitiki ndi njira yosinthira mphira yaiwisi kukhala zinthu zapulasitiki, zomwe zimatha kukhala zopindika pansi pamavuto.
Kusakaniza ndi njira yowonjezerera mankhwala opangira mphira kuti apange gulu la mphira, pomwezokutira ndi njira yopaka slurry pamwamba pa nsalu.
Kugudubuza ndi njira yopangira mafilimu kapena matepi otsirizidwa kuchokera ku mphira wosakanikirana. Kupsinjika kwamphamvu, kupsinjika kwakukulu, komanso kutalika panthawi yopuma kumawonetsa kukana kwa deformation, kukana kuwonongeka, ndi mawonekedwe amtundu wa rabara wovunda, motsatana.
Mphamvu yamisozi amaonetsa luso la zipangizo kukana kufalitsa mng'alu, pamenemphira kuuma ndikuvalayimira Kuthekera kwa mphira kukana kupunduka ndi kuvala pamwamba, motero.
Mpirakachulukidweamatanthauza kuchuluka kwa labala pa voliyumu iliyonse.
Kukana kutopa amatanthauza kusintha kwa kamangidwe ndi kachitidwe ka mphira pansi pa mphamvu zakunja za nthawi ndi nthawi.
Kukhwima kumatanthawuza njira ya kuyimitsidwa kwa mphira magazi, ndipo nthawi yakusasitsa imachokera ku kulimba kwa latex mpaka kutaya madzi m'thupi.
Shore A kuuma: Kuuma kumatanthauza kuthekera kwa mphira kukana kuwukiridwa ndi kuthamanga kwakunja, komwe kumagwiritsidwa ntchito kusonyeza kuchuluka kwa kuuma kwa mphira. Kulimba kwa m'mphepete mwa nyanja kumagawidwa kukhala A (kuyeza rabara yofewa), B (kuyeza mphira wokhazikika), ndi C (kuyeza labala wolimba).
Kulimba kwamakokedwe: Kulimba kwamphamvu, komwe kumadziwikanso kuti kulimba kwamphamvu kapena kulimba kwamphamvu, kumatanthauza mphamvu pagawo lililonse lomwe limagwiritsidwa ntchito pa mphira ikakokedwa, kufotokozedwa mu Mpa. Kulimba kwamphamvu ndi chizindikiro chofunikira choyezera mphamvu yamakina a rabara, ndipo kukula kwake kumapangitsanso mphamvu ya rabara.
Kuthamanga kwapakati pa nthawi yopuma, yomwe imadziwikanso kuti elongation, imatanthawuza chiŵerengero cha kutalika chomwe chimachulukitsidwa ndi kugwedezeka kwa mphira pamene ikukoka mpaka kutalika kwake koyambirira, kufotokozedwa ngati peresenti (%). Ndichizindikiro choyezera pulasitiki wa rabara, ndipo kutalika kwapamwamba kumasonyeza kuti mphirayo ali ndi mawonekedwe ofewa komanso pulasitiki wabwino. Kuti mphira igwire ntchito, imayenera kukhala ndi kutalika koyenera, koma kuchulukira sikulinso kwabwino.
Mtengo wobwereza, yomwe imadziwikanso kuti rebound elasticity kapena elasticity, ndi chizindikiro chofunikira choyezera kulimba kwa rabara. Chiyerekezo cha kutalika kwa rebound mpaka kutalika koyambirira mukamagwiritsa ntchito pendulum kuti mukhudze mphira pamtunda wina amatchedwa rebound rate, yomwe imawonetsedwa ngati peresenti (%). Kukula kwamtengo, kumapangitsa kuti mphira ukhale wolimba kwambiri.
Chotsani deformation okhazikika, yomwe imadziwikanso kuti deformation yokhazikika, ndi chizindikiro chofunikira choyezera kusungunuka kwa labala. Ndilo chiŵerengero cha kutalika chomwe chinawonjezeka ndi gawo lopunduka la mphira pambuyo potambasulidwa ndi kukokedwa ndi kuyimitsidwa kwa nthawi inayake (nthawi zambiri mphindi 3) mpaka kutalika koyambirira, kufotokozedwa ngati peresenti (%). Zing'onozing'ono zake, zimakhala bwino kuti mphira ikhale yolimba. Kuphatikiza apo, elasticity ya rabara imathanso kuyesedwa ndi kuponderezedwa kosatha.
