Ukuphahlazeka kwesici kuyisici esijwayelekile eduze kwesango ekubumbeni komjovo.Nokho, abantu abaningi badidekile, abakwazi ukubona iphutha noma ukwenza amaphutha okuhlaziya.Namuhla, sizokwenza incazelo.
Ibonakala ngemifantu ephuma esangweni iye endaweni ezungezile, ejulile futhi esobala ngokuvamile.Ngaphezu kwalokho, akukhona ukuqhekeka, kodwa imbangela yokuqhekeka yi-anisotropy yezinto eziqinile.
Ngesikhathi somjovo weglue esangweni eliphakathi, amandla okugeleza kwe-longitudinal (amandla aqinile) wezinto ezibonakalayo makhulu, kuyilapho amandla okugeleza okuphambene (amandla aqinile) mancane.Ukucindezeleka okukhiqizwa ukuncipha kuzodonsela umkhiqizo ekuqhekekeni, futhi ukuphuka kufanele kuqale endaweni ebuthakathaka, okungukuthi, indawo eguquguqukayo yezinto eziseduze nesango ngokucindezeleka okukhulu kwangaphakathi.
Isici se-crack yisici esibucayi kakhulu esibonakalayo, okungenakwenzeka neze ukudlula, ngakho-ke kufanele kuxazululwe.Umbono umi kanje:
1. Mayelana nezinto zokwakha
Ukuqina kwezinto kuyisizathu esiyinhloko samamaki wokuxoxa, ngakho-ke uma kunenqubo ende yemikhiqizo emikhulu, zama ukungakhethi izinto eziqinile kakhulu futhi ezinobude obuphansi ngesikhathi sekhefu, njenge-GPPS, AS, njll.
Ezisetshenziswa ezivamile, ukuhleleka kokuqina kusuka kokubuthakathaka kuye kokuqinile, kanye nokwenzeka kokuqhekeka kwe-seismic kusuka kokuncane kuye kokukhulu kumayelana: PE=>TPU=>PP=>PC=>I-ABS=>PA=>PVC=>PET=>I-POM=>PMMA=>AS=>PS.
Ngokuvamile, izinto ezinamaqembu aguquguqukayo zingathuthukisa iphethini yokudlidliza.Isibonelo, izinto zenjoloba, i-SEBS, i-EVA, i-K iyazuzisa.
2. Mayelana nesikhunta
Umklamo wesango weumjovo isikhuntaukhiye.Ngokuvamile, ngaphansi kwesakhiwo esinokucindezeleka okukhulu kwangaphakathi nokugeleza kwenqubo ende, iphethini yokudlidliza kwesango kulula ukwenzeka.Ngakho-ke, emikhiqizweni emikhulu, kulula ukwamukela uhlobo lwamasango amaningi namasango abanzi ukuze kuncishiswe ukumelana nokudla kwenjoloba futhi kube lula ukugeleza.
Ngokuvamile, isango lephoyinti kulula ukuvela imigqa yokudlidliza.Isango eliseceleni, isango labalandeli kanye nesango lethanga lingaphansi kancane.Kodwa amanye amasango, njengesango elingaphansi kwamanzi kanye nesango le-diaphragm, ngeke asetshenziswe ezakhiweni ezinjalo.Ngoba imikhiqizo eminingi enemigqa yokudlidliza iyimikhiqizo esobala, futhi asikho isidingo sokusebenzisa izimbobo zokuntywila noma izimbobo ze-diaphragm.
3. Mayelana namapharamitha: ukukalwa kwamapharamitha okuxazulula izimpawu zokuxoxa yile:
① Isivinini sokudubula esinensayo kanye nengcindezi yokudubula ephansi
②Isikhathi sokubamba ingcindezi emfushane
③Izinga lokushisa lesikhunta kufanele libe phezulu, njengempahla ye-PS.Izinga lokushisa lesikhunta lingasethwa libe ngama-degree angu-60.
4. Isifinyezo
Ukuphahlazeka kuyisici esivame kakhulu ekukhiqizeni imikhiqizo esobala eyenziwe ngezinto ze-GPPS.Uma singazinaki izindlela zokwelapha, ngaphezu kwamaphesenti angu-50 amaphutha noma wonke angase abe nesici.Ngokwazi izindlela ezingenhla kuphela lapho singaqeda khona amaphutha futhi siqinisekise ukukhiqizwa okuzinzile nokusezingeni eliphezulu.
