Kwicandelo lokufakelwa kombane, ukukhethwa kweenkqubo zolawulo lweentambo kubalulekile ukuqinisekisa ukhuseleko, ukusebenza kakuhle, kunye nokuqina. Phakathi kwezinto ezininzi ezikhoyo, iiplastiki eziqiniswe ngefayibha (FRP) kunye neeplastiki eziqiniswe ngefayibha yeglasi (GRP) zifumene ingqalelo enkulu. Zombini ezi zinto zingasetyenziselwa ukwenza iitreyi zentambo kunye neerakhi zeleli, kodwa iimpawu zazo ezikhethekileyo zizenza zilungele ukusetyenziswa ezahlukeneyo. Eli nqaku liza kuhlola umahluko phakathiIitreyi zekhebula ze-FRP kunye ne-GRP, egxininisa iimpawu zazo, iingenelo, kunye neemeko ezifanelekileyo zokusetyenziswa.

Ukuqonda i-FRP kunye ne-GRP

Ngaphambi kokuba sihlolisise umahluko phakathi kwezi zimbini, kubalulekile kuqala ukuqonda ukuba yintoni i-FRP kunye ne-GRP.

Iiplastiki eziQinisekisiweyo zeFiber (FRP)

Ii-fiber-reinforced polymer (FRP) composites zizinto ezidityanisiweyo ezine-polymer matrix kwaye ziqiniswe ngeefayibha. Ezi fayibha zingenziwa ngezinto ezahlukeneyo, kubandakanya iifayibha zeglasi, iifayibha zekhabhoni, iifayibha ze-aramid, okanye iifayibha zendalo. Eyona FRP isetyenziswa kakhulu kwiitreyi zekhebula yiplastiki eqinisiweyo yefayibha yeglasi (GRP). Nangona kunjalo, i-FRP inokuba nezinye iintlobo zeefayibha, ezinokuphucula iimpawu ezithile ezifana namandla, ubunzima, kunye nokumelana nezinto ezingqongileyo.

Iplastiki Eqinisiweyo Yeglasi Yeplastiki (i-GRP)

Iplastiki eqinisiweyo yeFiberglass (GRP) luhlobo olukhethekileyo lwezinto ezidityanisiweyo zeplastiki eqinisiweyo (FRP), esebenzisa iifayibha zeglasi njengokuqinisa. Iyaziwa ngomlinganiselo wayo ogqwesileyo wokuqina-ubunzima, ukumelana nokugqwala, kunye nokuqina. I-GRP isetyenziswa kakhulu kwiindawo ezahlukeneyo ezifana nokwakha, iimoto, kunye nokufakelwa kombane, kwaye ifanelekile ngakumbi kwiindawo apho ukusebenza kwezixhobo zemveli ezifana nentsimbi okanye i-aluminium kungafanelekanga.

Umahluko omkhulu phakathi kweetreyi zekhebula ze-FRP kunye ne-GRP

Nangona i-FRP kunye ne-GRP zihlala zisetyenziswa ngokutshintshana, kukho umahluko omkhulu phakathi kwazo ochaphazela ukhetho phakathiIitreyi zekhebula ze-FRPkunye neetreyi zekhebula ze-GRP.

1. Ukwakhiwa

Umahluko ophambili usekwe kwindlela ezibunjwe ngayo. I-FRP (iplastiki eqinisiweyo yefayibha) ludidi olubanzi oluquka imicu eyahlukeneyo, ngelixa i-GRP (iplastiki eqinisiweyo yefayibha yeglasi) ibhekisa ngokukodwa kwizinto ezenziwe kusetyenziswa imicu yeglasi. Olu mahluko luchaphazela iimpawu zoomatshini kunye nokusebenza kweetreyi zekhebula.

2. Amandla kunye Nokuqina

Zombini iitreyi zekhebula ze-FRP kunye ne-GRP zaziwa ngamandla azo kunye nokuqina kwazo. Nangona kunjalo, ngenxa yeempawu zefayibha yeglasi, iitreyi zekhebula ze-GRP ngokubanzi zinamandla aphezulu oomatshini. Oku kwenza i-GRP ibe lolona khetho lukhethwayo kwizicelo ezifuna amandla aphezulu okuthwala umthwalo. Kwelinye icala,Iitreyi zekhebula ze-FRPUkusebenzisa ezinye iintlobo zeefayibha kunokuba neempawu zamandla ezahlukeneyo, ezinokuba luncedo ngakumbi kwiimeko ezithile.

3. Ukumelana nokugqwala

Enye yezona nzuzo zibalulekileyo zeetreyi zekhebula ze-FRP kunye ne-GRP kukumelana kwazo nokugqwala. Nangona kunjalo, iitreyi zekhebula ze-GRP zifanelekile ngokukodwa kwiindawo ezinomswakama ophezulu, iikhemikhali, okanye amanzi anetyuwa. Iifayibha zeglasi kwi-GRP zinokumelana nokugqwala okugqwesileyo, zimelana nokugqwala kwezinto ezahlukeneyo ezigqwala, nto leyo ezenza zilungele ukusetyenziswa konyango lwaselwandle, lweekhemikhali, kunye namanzi amdaka. Iitreyi zekhebula ze-FRP nazo zinokumelana nokugqwala, kodwa ukusebenza kwazo kuyahluka ngokuxhomekeke kuhlobo lwefayibha esetyenzisiweyo.

4. Ubunzima

Iitreyi zentambo zeplastiki eziqinisiweyo zefayibha (FRP) zihlala zikhaphukhaphu kuneetreyi zentambo zefayibha (GRP). Oku kuyinzuzo kwizicelo apho ubunzima bubaluleke kakhulu, njengokusetyenziswa ngaphezulu okanye izakhiwo ezinemiqathango yobunzima. Ukunciphisa ubunzima be-FRP kunokunciphisa iindleko zokuthutha kunye nokufakela. Nangona kunjalo, xa kuthelekiswa ne-GRP, uhlobo olukhaphukhaphu lwe-FRP lunokuza neendleko zamandla athile oomatshini.

5. Iipropati zobushushu

Ukusebenza kobushushu lolunye umahluko ophambili phakathi kwe-FRP kunye ne-GRP. Iitreyi zekhebula ze-GRP zihlala zibonelela ngobushushu obungcono, nto leyo ezenza zifaneleke ngakumbi kwiindawo ezinokuguquguquka okukhulu kobushushu. Ziyakwazi ukumelana nobushushu obuphezulu ngaphandle kokuguquka okanye ukulahleka kobume besakhiwo.Iitreyi zekhebula ze-FRPKwelinye icala, isenokungasebenzi kakuhle njenge-GRP kwizicelo zobushushu obuphezulu, kuxhomekeke kwindibaniselwano ye-resin kunye nefayibha esetyenzisiweyo.

6. Ixabiso

Ixabiso lihlala liyinto ekufuneka iqwalaselwe kuyo nayiphi na iprojekthi. Ngokubanzi, iitreyi zekhebula ze-FRP zibiza kakhulu kuneetreyi zekhebula ze-GRP. Oku kungenxa yokuba i-FRP ineendleko eziphantsi zezinto eziluhlaza kunye nenkqubo yokuvelisa. Nangona kunjalo, inzuzo yokuqala yeendleko ze-FRP inokulinganiswa neendleko zokugcinwa kwexesha elide kunye nokutshintshwa, ingakumbi kwiindawo ezinzima apho i-GRP inokusebenza ngcono kune-FRP.

7. Izinto eziqwalaselwayo ngobuhle

Kwezinye iinkqubo, ubuhle beetreyi zekhebula buyinto ebalulekileyo. Iitreyi zekhebula zeplastiki eqinisiweyo ye-fiberglass (GRP) zihlala zinomphezulu ogudileyo kwaye zinokwenziwa ngemibala eyahlukeneyo, nto leyo eyenza zibonakale ngakumbi kwiindawo ezixhonywe phezulu. Iitreyi zekhebula zeplastiki eqinisiweyo ye-fiberglass (FRP), kwelinye icala, zinokuthambekela ngakumbi kwisitayile esiluncedo kwaye zisenokungafaneleki kuzo zonke iindawo.

Ukusetyenziswa kweeTreyi zeCable zeFRP kunye neGRP

Ukuqonda umahluko phakathi kweetreyi zekhebula ze-FRP kunye ne-GRP kunokunceda ekukhetheni imveliso efanelekileyo kwisicelo esithile.

Iitreyi zekhebula ze-FRP

Iitreyi zekhebula ze-FRP zilungele:
