Yintoni umahluko phakathi kombhobho wentsimbi engenamthungo oshushu kunye nombhobho wentsimbi engenamthungo obandayo ogoqwe kakuhle? Ingaba umbhobho wentsimbi engenamthungo oqhelekileyo ngumbhobho wentsimbi engenamthungo oshushu?
Iipayipi zentsimbi engenamthungo eziqengqelekayo ezibandayo zihlala zincinci ububanzi, kwaye iipayipi zentsimbi engenamthungo eziqengqelekayo ezishushu zihlala zinkulu ububanzi. Ukuchaneka kwepayipi yentsimbi engenamthungo eqengqelekayo ebandayo kuphezulu kunokwepayipi yentsimbi engenamthungo eshushu, kwaye ixabiso liphezulu kunelepayipi yentsimbi engenamthungo eshushu.
Iipayipi zentsimbi ezingenamthungo zahlulwe zaba ziipayipi zentsimbi engenamthungo eziqengqelekayo ezishushu (ezandisiweyo) kunye neepayipi zentsimbi engenamthungo ezitsalwa ngokubandayo (ezandisiweyo) ngenxa yeenkqubo zazo ezahlukeneyo zokwenza. Iipayipi ezitsalwa ngokubandayo (ezandisiweyo) zahlulwe zaba ziityhubhu ezingqukuva kunye neetyhubhu ezinemilo ekhethekileyo.
1) Iipayipi ezingenamthungo eziqengqelekayo ezishushu ngeenjongo ezahlukeneyo zahlulwe zaba ziipayipi zentsimbi eziqhelekileyo, iipayipi zentsimbi zebhoyila ezinoxinzelelo oluphantsi noluphakathi, iipayipi zentsimbi zebhoyila ezinoxinzelelo oluphezulu, iipayipi zentsimbi ye-alloy, iipayipi zentsimbi engatyiwayo, iipayipi zokuqhekeka kwepetroleum, iipayipi zentsimbi ye-geological kunye nezinye iipayipi zentsimbi. Iipayipi zentsimbi ezingenamthungo eziqengqelekayo ezibandayo (ezicoliweyo) zahlulwe zaba ziipayipi zentsimbi eziqhelekileyo, iipayipi zentsimbi zebhoyila ezinoxinzelelo oluphantsi noluphakathi, iipayipi zentsimbi zebhoyila ezinoxinzelelo oluphezulu, iipayipi zentsimbi ye-alloy, iipayipi zentsimbi engatyiwayo, iipayipi zokuqhekeka kweoyile kunye nezinye iipayipi zentsimbi, kunye neepayipi zentsimbi ezibhityileyo ezineedonga ezibhityileyo zekhabhoni, iipayipi zentsimbi ezibhityileyo ezineedonga ezibhityileyo, kunye neepayipi zentsimbi ezibhityileyo ezineedonga ezibhityileyo zentsimbi. Iipayipi zentsimbi, iipayipi zentsimbi ezimile okwesityu.
2) Ububanzi bangaphandle beepayipi ezingenamthungo ezigoqwe ngobushushu ezinobukhulu obahlukeneyo ngokubanzi bukhulu kune-32mm, kwaye ubukhulu bodonga buyi-2.5-75mm. Ububanzi bepayipi engenamthungo egoqwe ngobushushu bunokufikelela kwi-6mm, kwaye ubukhulu bodonga bunokufikelela kwi-0.25mm. Ububanzi bangaphandle betyhubhu eneendonga ezincinci bunokufikelela kwi-5mm, kwaye ubukhulu bodonga bungaphantsi kwe-0.25mm. Ukugoqwa okubandayo kunomlinganiselo ophezulu wokugoqwa okushushu.
3) Umahluko kwiinkqubo 1. Intsimbi eqengqelekayo ebandayo ivumela ukugoba kwecandelo, nto leyo enokusebenzisa ngokupheleleyo amandla okuthwala intsimbi emva kokugoba; ngelixa intsimbi eqengqelekayo eshushu ingavumeli ukugoba kwecandelo kwecandelo.
2. Izizathu zoxinzelelo olushiyekileyo lwentsimbi eqengqelekayo eshushu kunye nentsimbi eqengqelekayo ebandayo zahlukile, ngoko ke usasazo kwicandelo elinqamlezileyo nalo lwahlukile kakhulu. Usasazo olushiyekileyo loxinzelelo lwamacandelo entsimbi ebhityileyo eyenziwe ngodonga olubandayo lugobile, ngelixa usasazo olushiyekileyo loxinzelelo lwamacandelo entsimbi eqengqelekayo eshushu okanye edibeneyo lufana nefilimu.
3. Ukuqina kwe-torsional okukhululekileyo kwentsimbi eqengqelekayo eshushu kuphezulu kunokwentsimbi eqengqelekayo ebandayo, ngoko ke ukumelana kwe-torsional kwentsimbi eqengqelekayo eshushu kungcono kunokwentsimbi eqengqelekayo ebandayo.
4) Iingenelo ezahlukeneyo kunye nokungalungi Imibhobho engenamthungo eqengqelekayo ebandayo ibhekisa kwiishiti zentsimbi okanye imicu yentsimbi ecutshungulwa ibe ziintlobo ngeentlobo zentsimbi ngokutsala okubandayo, ukugoba okubandayo, kunye nokutsala okubandayo kubushushu begumbi.
Iingenelo: Isantya sokwenza siyakhawuleza, imveliso iphezulu, kwaye uqweqwe lonakele, kwaye lungenziwa ngeendlela ezahlukeneyo zokunqumla ukuze kuhlangatyezwane neemfuno zeemeko zokusetyenziswa; ukuqengqeleka okubandayo kunokubangela ukuguquka okukhulu kwentsimbi ngeplastiki, ngaloo ndlela kwandisa amandla okuvelisa intsimbi.
Iingxaki: 1. Nangona kungekho xinzelelo lwe-thermoplastic ngexesha lenkqubo yokwenza, kusekho uxinzelelo olushiyekileyo kwicandelo, oluya kuchaphazela ngokungathandabuzekiyo iimpawu zokugoba zentsimbi iyonke kunye nendawo; 2. Intsimbi yecandelo eligoqekileyo lihlala livulekile, elenza ukuqina kwe-free torsional yecandelo kube phantsi. .Kulula ukuyijika xa igoba, kulula ukuyigoba nokujika xa icinezelwe, kwaye inokumelana nokugoba okuphantsi; 3. Ubukhulu bodonga lwentsimbi egoqekileyo lincinci, kwaye iikona ezidibanisayo zeeplate azijiyanga, ngoko ke amandla okuthwala imithwalo exineneyo yendawo abuthathaka.
Iipayipi ezingenamthungo eziqengqelekayo ezishushu zihambelana neepayipi ezingenamthungo eziqengqelekayo ezibandayo. Iipayipi ezingenamthungo eziqengqelekayo ezibandayo ziqengqelekayo ngaphantsi kobushushu bokuphinda zisetyenziswe, kwaye iipayipi ezingenamthungo eziqengqelekayo ezishushu ziqengqelekayo ngaphezulu kobushushu bokuphinda zisetyenziswe.
Iingenelo: Ingatshabalalisa isakhiwo sokubumba se-ingot, icoce ingqolowa yentsimbi, isuse iziphene zesakhiwo, yenze isakhiwo sentsimbi sibe xineneyo, kwaye iphucule iimpawu zoomatshini. Olu phuculo lubonakala kakhulu kwicala lokuqengqeleka, ukuze intsimbi ingabi yi-isotropic ukuya kwinqanaba elithile; amaqamza, imifantu kunye nokungakhululeki okwenziwa ngexesha lenkqubo yokubumba nazo zinokudityaniswa kubushushu obuphezulu kunye noxinzelelo oluphezulu.
Iingxaki: 1. Emva kokuqengqeleka okushushu, izinto ezingezizo ezesinyithi (ikakhulu iisulfide kunye nee-oxides, kunye neesilicates) ngaphakathi kwentsimbi zicinezelwa zibe ngamaphepha amancinci, kwaye kwenzeka i-delamination (interlayer). I-Delamination yonakalisa kakhulu iipropati zokuxinana kwentsimbi kwicala lobukhulu, kwaye ukukrazuka kwe-interlaminar kunokwenzeka xa i-weld incipha. Uxinzelelo lwendawo olubangelwa kukuncipha kwe-weld ludla ngokufikelela amaxesha amaninzi kuxinzelelo lwe-yield point, olukhulu kakhulu kunoxinzelelo olubangelwa ngumthwalo;
2. Uxinzelelo olushiyekileyo olubangelwa kukupholisa okungalinganiyo. Uxinzelelo olushiyekileyo luxinzelelo lwangaphakathi oluzilinganisayo ngaphandle kwamandla angaphandle. Amacandelo ajikelezisiweyo ashushu ahlukeneyo anexinzelelo olushiyekileyo. Ngokubanzi, okukhona ubukhulu becandelo leprofayili yentsimbi bukhulu, kokukhona uxinzelelo olushiyekileyo lukhulu. Nangona uxinzelelo olushiyekileyo luzilinganisa, lusenempembelelo ethile ekusebenzeni kwelungu lentsimbi phantsi kwesenzo samandla angaphandle. Umzekelo, lunokuchaphazela kakubi ukuguquguquka, ukuzinza kunye nokumelana nokudinwa.
3. Iimveliso zentsimbi eziqengqelekayo ezishushu akulula ukuzilawula ngokubhekiselele kubukhulu kunye nobubanzi becala. Siqhelene nokwandiswa kobushushu kunye nokucutheka. Kuba ekuqaleni, nokuba ubude kunye nobukhulu bufikelele kwimigangatho, kuya kubakho umahluko othile ongalunganga emva kokupholisa kokugqibela. Okukhona umahluko ongalunganga mkhulu, kokukhona ubukhulu bukhula kwaye kokukhona ukusebenza kucacile.
