Umsebenti wekwakha tindlela letehlukene tekwakha ikakhulukati kugoba nekwelula lelishidi lelishiswe ngaphambilini ngekuya kwetidzingo letibekwe kusengaphambili ngekusebentisa emandla. Sidzingo lesiyinhloko kakhulu sekubumba kwenta lubondza lwemkhicito lufane ngendlela lekhonakala ngayo. Tizatfu letiyinhloko tekungalingani kwelubondza lwemikhicito nguleti: kwekucala, lizinga lekwelula incenye ngayinye yeshidi lelakhiwe lehlukile; kwesibili, bukhulu besivinini sekwelula, lokusho kutsi, lizinga lekugeleta kwegesi lekukhishwa kwemoya kanye nekukhuphuka noma sivinini sekuhamba kwesikhunta, luhlaka lwekucindzetela kanye ne plunger yekwelula ngaphambi kwekwelula. Kubumba ngulenye inchubo lebalulekile ngemuva kwekushisa kwemapuleti (emashidi), kufaka ekhatsi kulawula emapharamitha labalulekile ebuchwepheshe njengekwakha kushisa, kwakha umfutfo kanye nekwakha sivinini.
Kushisa Kwekwakha
Ngemuva kwekutsi tintfo, luhlobo lwenchubo kanye nemishini kuncunywe, lizinga lekushisa lekwakha liyintfo lebalulekile letsintsa lizinga lemkhicito, lelitsintsa ngco buncane lobukhulu, kusabalalisa bukhulu kanye neliphutsa lebukhulu bemkhicito, futsi liphindze litsintse elongation kanye nemandla e-tensile emkhicito, futsi lithinte ngisho nesivinini sekwakha. Ngako-ke, kufanele kutsatfwe njengalokubalulekile.
Kwakha Umfutfo
Umphumela wekucindzeteleka wenta lelishidi ligucuke, kepha lentfo inemandla ekumelana nekugucuka, futsi i-elastic modulus yayo iyancipha ngekukhula kwekushisa. Ngesikhatsi sekushisa kwekubumba, kuphela lapho kucindzeteleka lokubangelwa kucindzeteleka kulentfo kukhulu kune-elastic modulus yalentfo kulelizinga lekushisa lapho khona lentfo ingakhubateka. Uma umfutfo losetjentiswa ngesikhatsi lesitsite sekushisa ungakeneli kukhicita kukhula lokwenele kwalentfo, kubumba kungakhiwa kahle kuphela ngekukhulisa umfutfo wekubumba noma kukhulisa lizinga lekushisa lekubumba. Ngenca yekutsi i-elastic modulus yetintfo letehlukene yehlukile futsi inekuncika lokuhlukile ekushiseni, umfutfo wekubumba uyahluka ngeluhlobo lwe polymer (kufaka ekhatsi sisindvo se molecule lesihlobene), bukhulu bemashidi kanye nekushisa kwekubumba.
Sivinini Sekwakha
Tizatfu letiyinhloko tekungalingani kwelubondza lwemikhicito nguleti: kwekucala, lizinga lekwelula incenye ngayinye yeshidi lelakhiwe lehlukile; kwesibili, bukhulu besivinini sekwelula, lokusho kutsi, lizinga lekugeleta kwegesi lekukhishwa kwemoya kanye nekukhuphuka noma sivinini sekuhamba kwesikhunta, luhlaka lwekucindzetela kanye ne plunger yekwelula ngaphambi kwekwelula. Ijubane lokwakha libhekisela ijubane umdvwebo ipuleti (ishidi). Kukhulisa sivinini sekwakha kungenta umjikeleto wekwakha ube mfishane futsi kuyasita ekwenteni ncono umkhicito. Kepha, sivinini sekwakha lesengetiwe sitawutsintsa lizinga lemkhicito.
Siyati kutsi imininingwane incumela imphumelelo nobe kwehluleka, ngako-ke siphatsa umkhicito ngamunye ngendlela lenhle kakhulu futsi setama kuba ngulabaphelele ngendlela lesingakhona ngayo.
