Izincamathelisi ezintsha ezinobunzima obuphezulu: Njani I-HTBN kuthintela ukungaphumeleli kokudinwa
Yintoni ukusilela kokudinwa okunamathelayo?
Ukungasebenzi kakuhle kokudinwa okunamathelayo kwenzeka xa i-bond ibuthathaka okanye yaphuka emva kokujongana noxinzelelo oluphindaphindayo ngokuhamba kwexesha. Oku ukubona kwiiprojekthi ezininzi zobunjineli nezokwakha. Ezona zinto zixhaphakileyo ziquka:
- Ukulayisha ngesantya esiphezulu, oko kuthetha ukuba ikhonkco lijongene nokutyhala, ukutsala, okanye ukungcangcazela okuphindaphindiweyo.
- Ukulayisha okungaguqukiyo, okukwabizwa ngokuba yi-creep, apho amandla angaguqukiyo enza ukuba i-adhesive iguquguquke kancinci.
- Ukujikeleza kobushushu, okwenzeka xa utshintsho lobushushu lubangela ukuba izinto zande kwaye zinciphe.
- Ukwaluphala kwendalo, apho umswakama, ilanga, okanye iikhemikhali zonakalisa kancinci kancinci iglu.
Olu phononongo lubonisa ukuba amalungu anomphetho omnye afumana iindlela ezahlukeneyo zokusilela phantsi komthwalo wokudinwa, apho ukusilela okudibeneyo/okuncamathelayo kubonisa ubomi bokudinwa obandayo kunye nokugqithisana okude, ngelixa ukusilela kokunamathela kubonisa iindlela ezahlukeneyo.
Kufuneka uziqonde ezi zizathu kuba zinokubangela ukuqhekeka okanye ukuqhekeka komaleko wokuncamathelisa. Ekuhambeni kwexesha, ezi qhekeko zincinci ziyakhula kwaye zenze i-bond ibe buthathaka. Ukuba awuzilungisi ezi ngxaki, iprojekthi yakho inokungaphumeleli ngokukhawuleza kunokuba bekulindelwe.
Kutheni ukudinwa kunciphisa ubomi beprojekthi
Ukungaphumeleli kokudinwa akupheleli nje ekubangeleni iingxaki ezincinci. Kunokubangela iingxaki ezinkulu kwiprojekthi yakho. Xa i-adhesive bond isilela, unokufuna ukulungisa okanye ukutshintsha iindawo, nto leyo ebiza ixesha nemali. Ukungaphumeleli kokudinwa kwe-adhesive kunokukhokelela ekuphelelweni kwe-bond ngaphambi kwexesha, nto leyo ebangela ukulungiswa okubizayo kunye nokutshintshwa. Ukukhetha i-adhesive kubalulekile; umzekelo, ii-epoxies eziqinileyo zaziwa ngendlela yazo yokuqhekeka, nto leyo eyomeleza ukuqina. Ii-polyurethanes, nangona ziguquguquka, zinokufunxa ukungcangcazela kwaye zilungele ukwanda kobushushu, zizenze zilungele ukusetyenziswa ngoxinzelelo olwahlukeneyo. Unyango olufanelekileyo lomphezulu lubalulekile ukuthintela ukungaphumeleli kwe-adhesive, kwaye ubukhulu bomaleko we-adhesive kufuneka buphuculwe ukuze kuthintelwe ukungaphumeleli kwe-brittle. Ukutyala imali kwi-adhesives ezisemgangathweni ophezulu kunokunciphisa kakhulu iindleko zokulungisa kwixesha elizayo.
Usenokungaziboni iintsilelo zokudinwa ngoko nangoko. Kunzima ukuzibona kwangethuba, nto leyo eyonyusa umngcipheko wokuqhekeka ngequbuliso. Ezi ntsilelo zinokunciphisa ukusebenza kwamalungu kwaye zibangele nemiphumo emibi kakhulu. Kwezinye iimeko, iintsilelo zokudinwa zibanga i-50-90% yazo zonke iintsilelo kwiindawo ezinamatheleyo. Ukwahlulwahlulwa, okanye ukwahlulwa kweengqimba, kunokwenzeka xa iintsilelo zikhula kwi-adhesive. Oku kwenza ukuhlolwa nokulungiswa kube nzima ngakumbi kwaye kunokukhokelela ekuphulweni ngokukhawuleza.
