Kodi tayala: Kodi zochita za

Mphira - zakuthupi odziwika kuti ntchito pafupifupi muzochitika zones za moyo wa munthu. Medicine, ulimi, makampani simungakhoze kuchita popanda polima izi. kugwiritsa ntchito matayala mu njira zambiri mafakitale. N'chiyani chimachititsa izi ndi zimene ndi makhalidwe ake, limafotokoza nkhani.

ndi tayala Kodi

Mphira ndi polima kukhala elasticity mkulu. akuphatikizapo ukufanizidwa ndi mosintha oyenerera maatomu unyolo mpweya angongole sulfure.

Mu boma yachibadwa unyolo mpweya ndi wokhotakhota maonekedwe. Ngati mphira Tambasula, unyolo mpweya unwind. Luso kutambasula mwamsanga kubwerera ku mawonekedwe akale wapanga singasiyanitsidwe m'madera ambiri zakuthupi ngati jombo.

N'chiyani chimachititsa izo? Childs, mphira anawakonzera kusakaniza mphira ndi wothandizila vulcanizing. Pambuyo Kutentha kwa kutentha anakhumba, osakaniza thickens.

Mosiyana ndi mphira mphira

Jombo ndi mphira - mkulu kulemera ma polima maselo, masoka kapena analandira synthetically. zinthuzi yodziwika ndi katundu physico-mankhwala ndi njira yopanga. Natural mphira ndi chinthu chopangidwa kuchokera ku madzi nkhuni otentha - Zodzitetezela. Iwo zichokela ku makungwa pamene kuonongeka. Kupanga mphira opangidwa ndi polymerization wa styrene, neoprene, butadiene, isobutylene, chloroprene, nitrile akiliriki acid. Pamene vulcanization aumbike matayala kupanga mphira.

kuchita mitundu yosiyanasiyana ya mphira chiyani? Pakuti mitundu ina ya angapange ndi zinthu organic, kulola kupeza zinthu zofanana ndi mphira achilengedwe.

katundu mphira

Mphira ndi mosalekeza zinthu zomwe ali katundu zotsatirazi:

1. Mkulu elasticity - luso kusintha ndi mapindikidwe lalikulu mu lonse kutentha osiyanasiyana.
2. Elasticity ndi mawonekedwe kukhazikika pa mitundu yaing'ono.
3. Amorphousness - mosavuta olumala ndi pang'ono imachepa.
4. The softness wachibale.
5. Osauka zimatenga madzi.
6. Mphamvu ndi avale kukana.
7. Malinga mtundu wa matayala mphira akhoza yodziwika ndi madzi, mafuta, mafuta, kutentha kukana ndi kukana mankhwala, kuwala ndi cheza ionizing.

kenako tayala wotaya katundu ndi wotaya mawonekedwe ake, omwe amasonyeza m'chiwonongeko ndi kuchepa mphamvu. The moyo utumiki wa mankhwala mphira amadalira zinthu ntchito ndipo akhoza zimasiyana masiku angapo zaka zingapo. Ngakhale nthawi yaitali yosungirako tayala mibado amakhala unusable.

mphira Kupanga katundu

Matayala umatulutsa vulcanization ya labala ndi Kuwonjezera zosakaniza. Childs, 20-60% Unyinji wa mphira kuti kukonzedwa. zigawo zina za mphira zikuchokera - fillers, curatives, accelerators, plasticizers, antioxidants. Kulemera zikuchokera amathanso zidzawonjezedwa utoto, zonunkhiritsa, modifiers, retardants malawi ndi zigawo zina. Zogwiritsira zigawo anatsimikiza ndi katundu chofunika, zinthu opaleshoni, sayansi ya ntchito mphira chomaliza mankhwala ndi kuwerengetsera zachuma. Mu njira iyi, izo amalenga mphira apamwamba.

Kodi zimapangitsa mankhwala mphira theka-yomalizidwa? Chifukwa chaichi, ntchito m'mafakitale mphira kusanganikirana luso ndi zigawo zina akakhale opanga wapadera kapena odzigudubuza, anafuna zotsimikizira mankhwala theka-kusasanyiwa, ndi kudula wotsatira ndi kudula kunja. Mu mkombero kupanga ntchito makina, autoclaves, ng'oma ndi mumphangayo vulcanizer. Mphira pawiri amamangiriridwa ku plasticity mkulu, chifukwa chimene tsogolo la mankhwala amatenga pa mawonekedwe ankafunila.

mankhwala mphira

Pakali pano, mphira ntchito masewera mankhwala, zomangamanga, ulimi, kupanga. Chiwerengero cha katundu, chopangidwa kuchokera ku mphira, oposa 60 zikwi. Zosiyanasiyana. Wotchuka kwambiri wa iwo - zisindikizo, absorbers mantha, yamachubu, gaskets, mankhwala ena omatira, rubberized ❖ kuyanika, kumalumikiza zipangizo.

mankhwala mphira ntchito lalikulu zedi mu ndondomeko mafakitale. Nkhanizi ndi yofunika kupanga magolovesi, nsapato, malamba, madzi nsalu, malamba conveyor.

Ambiri mwa mphira opangidwa ntchito popanga matayala.

Mphira makampani tayala

Mphira ndi nkhani yaikulu kupanga matayala a galimoto. ndondomeko limayamba ndi tsiku lokonzekera mphira osakaniza mphira zachilengedwe ndi kupanga. Kenako, anawonjezera silika, mpweya wakuda, ndi zina zosakaniza mankhwala kwa misa mphira. Pambuyo kusanganikirana mokwanira, osakaniza anatumidwa ndi conveyor lamba mu ng'anjo. linanena bungwe ndi mphira Mzere wa kutalika ena.

Chotsatira ndi gumming chingwe. Zingwe nsalu ndi tizitsulo udzathiridwa mphira misa otentha. M'njira imeneyi anapanga mkati, nsalu ndi tayala lamba wosanjikiza.

N'chiyani chimachititsa tayala mphira? Onse opanga matayala galimoto ntchito njira zosiyana ndi luso mphira kupanga. Kupereka chotsirizidwa mphamvu ndiponso kudalirika akhoza kuwonjezeredwa plasticizers osiyanasiyana ikuthandizira fillers.

Turo kupanga ntchito mphira achilengedwe. Kuwonjezera ake kwa mphira zikuchokera amachepetsa Kutentha kwa tayala. Ambiri pawiri mphira amatenga mphira kupanga. chigawo Izi zimamupatsa sichisinthasinthanso tayala ndi kukhalabe olimba katundu wolemera.
