Isishwankathelo: Isakhiwo sentsimbi sisakhiwo esenziwe ngezinto zentsimbi kwaye sesinye sezona ntlobo ziphambili zezakhiwo zokwakha. Isakhiwo sentsimbi sineempawu zokuba namandla aphezulu, ubunzima obulula, ukuqina okuhle ngokubanzi, amandla okuguquka okunamandla, njl.njl., ngoko ke singasetyenziselwa ukwakha izakhiwo ezinkulu, eziphakamileyo kakhulu nezinzima kakhulu. Iimfuno zezinto zokwakha zentsimbi Isalathisi samandla sisekelwe kumandla okuvelisa intsimbi. Emva kokuba iplastiki yentsimbi idlule kwinqanaba lokuvelisa, inepropathi yokuguquka okubalulekileyo kweplastiki ngaphandle kokuqhekeka.
Zithini iimpawu zesakhiwo sentsimbi
1. Amandla aphezulu ezinto zokwakha kunye nobunzima obulula. Intsimbi inamandla aphezulu kunye ne-elastic modulus ephezulu. Xa ithelekiswa nekhonkrithi kunye nomthi, umlinganiselo wayo wobunzima bokuvelisa uphantsi kakhulu. Ke ngoko, phantsi kweemeko ezifanayo zoxinzelelo, isakhiwo sentsimbi sinendawo encinci enqamlezileyo, ubunzima obulula, kulula ukuthuthwa nokufakelwa, kwaye sifanelekile kwizakhiwo ezineendawo ezinkulu, ukuphakama okuphezulu kunye nemithwalo enzima.
Iimfuno zezinto eziphathekayo zesakhiwo sentsimbi
1. Amandla Amandla esinyithi aqulunqwe ngumda we-elastic σe, umda we-yield σy, kunye nomda we-tensile σu. Uyilo lusekelwe kumandla e-yield esinyithi. Amandla e-yield aphezulu anokunciphisa ubunzima besakhiwo, onge intsimbi kwaye anciphise iindleko zokwakha. Amandla e-tensile ou luxinzelelo oluphezulu olunokumelana nentsimbi ngaphambi kokuba yonakale. Ngeli xesha, isakhiwo silahlekelwa kukusetyenziswa kwaso ngenxa yokuguquguquka kweplastiki enkulu, kodwa isakhiwo siyawohloka kakhulu ngaphandle kokuwa, kwaye kufuneka sikwazi ukuhlangabezana neemfuno zesakhiwo ukumelana neenyikima ezingaqhelekanga.

2. Ukuqina kweplastiki
Ukuqina kwentsimbi ngokubanzi kubhekisa kwimpawu yokuba emva kokuba uxinzelelo ludlule kwinqanaba lemveliso, lunokuguquguquka okukhulu kweplastiki ngaphandle kokuqhekeka. Iimpawu eziphambili zokulinganisa amandla okuguquguquka kweplastiki yentsimbi yi-elongation ō kunye ne-cross-sectional shrinkage ψ.
3. Ukusebenza kokugoba okubandayo
Ukusebenza kwentsimbi egobileyo kubanda yindlela yokulinganisa ukumelana kwentsimbi neentanda xa iplastiki igobile ngenxa yokugoba kubushushu begumbi. Ukusebenza kwentsimbi egobileyo kubanda kukusebenzisa iimvavanyo zokugoba kubanda ukuvavanya ukusebenza kwentsimbi egobileyo phantsi kwenqanaba elithile lokugoba.
4. Ukuqina kwempembelelo
Ukuqina kwentsimbi kubhekisa kubuchule bentsimbi bokufunxa amandla e-kinetic oomatshini ngexesha lenkqubo yokuqhekeka phantsi komthwalo wempembelelo. Yimpawu yoomatshini elinganisa ukumelana kwentsimbi nomthwalo wempembelelo, okunokubangela ukwaphuka okubuthathaka ngenxa yobushushu obuphantsi kunye noxinzelelo. Ngokubanzi, isalathisi sokuqina kwempembelelo yentsimbi sifunyanwa ngovavanyo lwempembelelo lweesampuli ezisemgangathweni.

6. Ukuqina
Kukho izinto ezininzi ezichaphazela ukuqina kwentsimbi. Eyokuqala kukuba ukumelana nokugqwala kwentsimbi akukuhle, kwaye kufuneka kuthathwe amanyathelo okukhusela ukuthintela ukugqwala kunye nokugqwala kwentsimbi. Amanyathelo okukhusela aquka: ukugcinwa rhoqo kwepeyinti yentsimbi, ukusetyenziswa kwentsimbi egqunyiweyo, kunye namanyathelo okukhusela akhethekileyo xa kukho izinto ezinamandla ezigqwalisayo ezifana ne-asidi, i-alkali, kunye netyuwa. Umzekelo, isakhiwo seqonga elingaselunxwemeni sisebenzisa amanyathelo "okukhusela i-anodic" ukuthintela ukugqwala kwejakethi. Ii-ingots ze-zinc zinamathele kwijakethi, kwaye i-electrolyte yamanzi olwandle iya kuqala ukugqwala ii-ingots ze-zinc, ngaloo ndlela ifezekisa umsebenzi wokukhusela ijakethi yentsimbi. Okwesibini, kuba amandla atshabalalisayo entsimbi aphantsi kakhulu kunamandla exesha elifutshane phantsi kobushushu obuphezulu kunye nomthwalo wexesha elide, amandla entsimbi exesha elide phantsi kobushushu obuphezulu bexesha elide kufuneka alinganiswe. Intsimbi iya kuba lukhuni kwaye ibe buthathaka ngokuhamba kwexesha, nto leyo "eyaluphalayo". Ukuqina kwentsimbi phantsi komthwalo wobushushu obuphantsi kufuneka kuvavanywe.
