Taayir xumbo leh oo ka samaysan walxo balaastiig ah oo xumbo leh, oo leh xasilloonida cabbirka, heerka isbeddelka <1%.Iyo xasiloonida kiimikada, anti-corrosion iyo anti-gabowga, gaar ahaan awoodda xal organic, acid xoog leh, sifooyinka daxalka alkali daciif ah.Taayirka xumbada leh ee ka samaysan caag xumbo leh ayaa leh sifooyinka miisaanka fudud, alaabta badbaadinta, nuugaya culeyska saameynta, kuleylka kulaylka iyo dhawaaqa dhawaaqa iyo xoogga sare sababtoo ah jiritaanka goobooyin.
Taayirada xumbada leh maaha inay ka werweraan taayirada daloolsan, maaha inay bamgareeyaan.Taayirka pneumatic, oo sidoo kale loo yaqaano taayir godan, waxaa loola jeedaa godka gudaha ee taayirku wuxuu u baahan yahay in lagu buuxiyo gaas cadaadis leh, wuxuuna ilaalin karaa cadaadiska gudaha.Waxaa jira taayirro tuubo iyo taayirro aan tuubo lahayn.Taayirka noocan ahi waxa uu leeyahay barkin wanaagsan iyo wax qabad qoyaan iyo iska caabin yar oo rogrogis ah sababtoo ah daloolka gudaha waxaa ka buuxa gaas ama dareere.
Taxanaha xumbo Pu, sifooyinkiisu waa: aan sun ahayn, dhadhan la'aan, kulayl la'aan, habka goobta dhawaaqa fudud, tayada alaabta deggan, fududahay in la sayid;
Miisaanka taayirrada la soo saaray waa 1/2 ee taayirada caagga ah;
Xiro caabbinta waa 6 jeer taayirrada caagga ah;
Heerka foorarsiga waa 5 jeer taayirada caagga ah;
Waxay ku xajinaysaa bartinimadeeda oo laga jaray 50 darajo,
Acid iyo caabbinta alkali, caabbinta daxalka waa 3.5 jeer taayirrada caagga ah;
Balaastigu 3 jeer ayuu ka sarreeyaa taayirada caagga ah;
Waxaa loo habeyn karaa iyadoo loo eegayo adkaanta, cufnaanta, qeexida dhammaan noocyada taayirada.
Farqiga u dhexeeya giraangiraha pu wheel iyo caagga
● Dabeecad kala duwan
◆ Shaagagga caagga ah: taayirrada caagga ah waxa ay ku jiraan gaadiid ama mashiinno kala duwan oo lagu ururiyey dhulka wareegta ah alaabada taayirrada caagga ah ee laastikada ah.
◆ PU wheel: pu wheel.
● Sifooyin kala duwan
1. Tilmaamaha giraangiraha caagga ah:
(1) Marka badeecooyinka caagga ah la sameeyo, isku-xirnaanta elastomers lama tirtiri karo ka dib cadaadis sare oo cadaadis ah.Marka badeecooyinka caagga ah laga sooco caaryada, hoos u dhaca elastomerku aad ayuu u deggan yahay (hoos u dhaca caaggu wuu kala duwan yahay hadba nooca caagga).elastomer-ku waa inuu si tartiib ah u degaa muddo ka dib.
Sidaa darteed, bilowga naqshadeynta alaabta caagga ah, labadaba caanaha iyo caaryada, waa inay si taxadar leh u xisaabiyaan heerka isuduwidda.Haddii kale, cabbirka alaabtu waxay noqon doontaa mid aan degganayn, tayada alaabtu waxay noqon doontaa mid aad u hooseeya.
(2) Rubberku waa elastomer heerkulbeeye ah, balaastiigguna waa elastomer heerkulbeeye.Heerkulka kala duwan ee qaabaynta caagga iyo vulcanization aad ayey u kala duwan yihiin iyadoo ku xiran nooca ugu muhiimsan ee sulfide oo laga yaabo inay xitaa saameyn ku yeelato isbedelka cimilada iyo heerkulka gudaha iyo huurka.Sidaa darteed, xaaladaha wax soo saarka ee alaabta caagga ah waxay u baahan yihiin in la hagaajiyo wakhti kasta.Haddii kale, waxaa jiri kara kala duwanaansho xagga tayada alaabta.
2. Tilmaamaha giraangiraha PU: laastikada waxay ciyaari kartaa saameyn qoyan oo gaar ah (xitaa ka fiican giraangiraha la buufiyo), xajin wanaagsan, ma fududa in la simbiriiro, xirto badan oo adkaysi u leh, waxqabadka raaxada leh ayaa wanaagsan.
