Kade nna ai aten hta, PetroChina sawk sagawn hpung gaw, shanhte woi awn ai mungdan ting na R&D bungli masing ni, synthetic rubber hpaga lam a matu ahkyak ai hpaji masa ni gaw, shawng nnan na mahtai ni hpe lu la sai. hpe tsun wa sai.
Ndai lam gaw, shagan amyu bawsang garan ginhka ai butyl/brotomyl rubber synthesis hte double-B tire hkyen lajang ai hpaji hpe n-gun jaw ai lam ni zawn re ai madung hpaji masa ni hta hpaji masa kaba ni hpe lu la sai lam tsun shapraw da ai.
Ndai lam hpe chye ai masha langai tsun ai hta, ndai masing hpe Miwa mung Petroleum hte Petrochemical sawk sagawn hpung ni woi awn ai..
Ndai bungli galaw ai hpung ni hta, Miwa Hpaji Dap na Changchun Yinghua hpung, Dalian Dakkasu, Tsinghua Dakkasu, Shandong Jinyu hpaga hpung, Yiweiyi Rubber sawk sagawn hpung hte Zheang Xinhui{1}} zawn re ai wuhpung 7 lawm ai.
Star-type branched butyl rubber gaw butyl rubber a n-gun kaba ai arung arai langai rai nna, n-gun ja ai capsules. a prat hpe galu kaba wa hkra ahkyak ai lit nga ai.
Shi a galaw shapraw ai hpaji masa gaw yak hkak ai, masa lam ni gaw grai sawng ai, polymerization nbung katsi ai lam gaw-100℃daram rai nga ai C{1}} Shawng de gaw, Miwa mung hta kungkyang ai hpaji masa ni hte arung arai ni n nga ai.
Ndai masing hpe hparan ai lam hta, masing hpung gaw polymerization raw arung arai, polymerization galaw ai ladat hte polymerization formula ni hpe sawk sagawn ai lam hpe galaw hpang wa ai, shagan zawn re ai lakung lakying ni hpe garan ginhka ai butbber hkyen lajang ai hpaji sawk sagawn hpaji hpe hkum tsup hkra gyin shalat wa ai.
Vulcanized capsules ni gaw tyre galaw ai lam a madung daw ni rai nna, tyre a quality hte manu jahpu hpe grai hkra machyi shangun ai.}.
Shiga ni hta tsun da ai hte maren, ya aten hta Miwa mungdan hta vulcanized capsule arung arai ni hpe bai lang ai jahpan gaw 450 lang daram rai nga ai, dai gaw maigan mungdan ni a rawt jat galu kaba wa ai madang hte naw tsan nga ai.
Miwa mung Petroleum hte Petrochemical sawk sagawn hpung ni tsun ai hta, ndai nnan rawt jat galu kaba wa ai shagan ni a branched butyl rubber gaw, n-gun ja ai capsule arung arai ni a shinggyim masha ni a prat hpe 15% jan jat wa shangun ai, 527 lang.}.
