Kayan fasaha na fasaha suna da ƙarfin injina mai ƙarfi, tauri, juriya, juriya mai zafi, da ƙarancin ƙima. Dangane da haɓakawa, yana da kyakkyawan kayan aikin lantarki da na thermal insulator.
Bayan girgizar zafi, wanda ke saurin ɗumawa wanda ke sa yumbu ya faɗaɗa, yumbu na iya ɗaukar sauye-sauyen zafin jiki kwatsam ba tare da tsagewa, karye, ko rasa ƙarfin injinsa ba.

Thermal shock, wanda kuma aka fi sani da "Rushewar thermal," shine tarwatsewar duk wani abu mai ƙarfi wanda ya haifar da canjin zafin jiki kwatsam. Canjin zafin jiki na iya zama mara kyau ko tabbatacce, amma dole ne ya zama mahimmanci a kowane yanayi.
Matsalolin injina suna samuwa ne tsakanin abin waje (harsashi) da na ciki (core) yayin da yake zafi ko sanyi a waje fiye da na ciki.
Kayan yana da lalacewa mara misaltuwa lokacin da bambancin zafin jiki ya wuce ƙayyadaddun ƙira. Abubuwa masu zuwa suna da tasiri akan wannan ƙimar zafin jiki mai mahimmanci:

  • Matsakaicin haɓaka haɓakar thermal na linzamin kwamfuta

  • Ƙarfafawar thermal

  • Rabon Poisson

  • Na roba modules

 

Canza ɗaya ko fiye na waɗannan na iya sau da yawa inganta aiki, amma kamar yadda yake tare da duk aikace-aikacen yumbura, girgizar zafi ɗaya ce kawai na lissafin, kuma duk wani canje-canje dole ne a yi la'akari da shi a cikin mahallin duk buƙatun aiki.


Lokacin zayyana kowane samfurin yumbu, yana da mahimmanci a yi la'akari da buƙatun gabaɗaya kuma akai-akai nemo mafi kyawun sasantawa.


Girgizawar zafi akai-akai shine babban dalilin gazawa a aikace-aikacen zafi mai zafi. Ya ƙunshi abubuwa uku: faɗaɗa thermal, thermal conductivity, da ƙarfi. Canje-canjen zafin jiki mai sauri, sama da ƙasa, yana haifar da bambance-bambancen zafin jiki a cikin ɓangaren, kama da fashewar da aka yi ta hanyar shafa cube ɗin kankara a kan gilashin zafi. Saboda bambance-bambancen fadadawa da raguwa, motsi yana haifar da tsagewa da gazawa.

Babu mafita mai sauƙi ga matsalar girgizar zafi, amma shawarwari masu zuwa na iya zama da amfani:

  • Zaɓi matakin abu wanda ke da wasu halaye na girgiza zafin zafi amma ya dace da buƙatun aikace-aikacen. Silicon carbides suna da ban mamaki. Abubuwan da aka yi da Alumina ba su da kyawawa, amma ana iya inganta su tare da ƙirar da ta dace. Samfuran da ba su da ƙarfi gabaɗaya sun fi waɗanda ba su da ƙarfi saboda suna iya jure canjin yanayin zafi.

  • Kayayyakin da ke da bangon bakin ciki sun fi waɗanda ke da bangon kauri. Har ila yau, kauce wa babban kauri mika mulki a ko'ina cikin sashe. Sassan sashe na iya zama fin so saboda suna da ƙarancin taro da ƙirar da aka riga aka fashe wanda ke rage damuwa.

  • Ka guji amfani da sasanninta masu kaifi, saboda waɗannan wurare ne na farko don tsagewa. Guji sanya tashin hankali akan yumbura. Za a iya ƙirƙira sassan don a riga an matsa musu don taimakawa rage wannan matsalar. Bincika tsarin aikace-aikacen don ganin ko zai yiwu a samar da canjin zafin jiki a hankali, kamar ta hanyar dumama yumbu ko rage yawan canjin zafin jiki.
