Ungazikhetha kanjani izinhlobo ezifanele ze-hemc?

Ukukhetha okuhlukahlukene kwe-hydroxyyethyllyl (hemc) okulinganiselayo kudinga ukuqonda izinto ezahlukahlukene ezifana namakhemikhali alo, uhlelo lokusebenza, amazinga wekhwalithi, kanye nezidingo ezithile zephrojekthi noma isicelo.

1. Qonda i-hemc:

1.1 Izakhiwo zamakhemikhali:
I-Hemc iyi-ether engekho i-ether ethathwe ku-cellulose, i-polymer yemvelo etholakala ezitshalweni. Ihlelwe ngokwelapha iselula nge-alkali bese iphendula nge-ethylene oxide ne-methyl chloride. I-Hemc iyancibilika emanzini abandayo futhi yakha isixazululo esicacile, esibonakalayo.

1.2 Isicelo:
I-Hemc isetshenziswa kabanzi emikhakheni ehlukahlukene kufaka phakathi ukwakhiwa, amakhambi, izimbobo, ukunamathela kanye nemikhiqizo yokunakekelwa komuntu. Imisebenzi yayo eyinhloko ifaka phakathi ukuqina, ukugcinwa kwamanzi, ukwakheka kwamafilimu nokuzinza.

1.3 Izinga lekhwalithi:
Lapho ukhetha izinhlobonhlobo ze-hemc, kufanele uqinisekise ukuthi ihlangabezana namazinga afanele afanele, anjenge-ISO 9001 noma amazinga athile embonini. Lezi zindinganiso ziqinisekisa ubumsulwa bomkhiqizo, ukungaguquguquki kanye nokusebenza.

2. Izici okufanele zicatshangelwe:

2.1 I-Viscosity:
Izinhlobo zeHemc zitholakala kumabanga okufanekisa ahlukene, kusuka kokuphansi kuya phezulu. Izidingo ze-Viscosity zincike ohlelweni kanye nokuvumelana okufisayo kwesisombululo noma ukwakhiwa. Isibonelo, ibanga eliphakeme le-viscosity lilungele ukuqina kokuqina noma izinamathiseli, kanti ibanga eliphansi lensizwa lingakufanelekela kangcono ukwakhiwa kwemithi.

2.2 Usayizi wezinhlayiyana:
Ubukhulu bezinhlayiyana ze-hemc buthinta ukuhanjiswa kwalo kanye nokusebenza kwalo kuzicelo ezahlukahlukene. Izinhlayiya ezinhle zivame ukusabalalisa kalula emanzini futhi zinganikeza izakhiwo ezingcono ze-rheological ekwakhiweni okuthile.

2.3 Ukugcinwa kwamanzi:
Eminye yemisebenzi esemqoka ye-hemc ukugcinwa kwamanzi, okubaluleke kakhulu ukuthola izicelo ezifana nodaka olususelwa kuso usimende noma i-stucco. Ikhono likaHemc lokugcina amanzi futhi ukuvimba ukomiswa ngaphambi kwesikhathi kuthinta ukucubungulwa nokungathowuwa kwalezi zinto.

2.4 Ukwakheka kwefilimu:
Ezinkotsheni nasemikhiqizweni yokunakekelwa komuntu siqu, i-hemc ivame ukusetshenziselwa ukwakha ifilimu elincanyana, elifanayo elilinganayo ebusweni. Ukusebenza okwakha amafilimu kwe-hemc kuthintwa yizinto ezifana nesisindo se-molecular kanye degree of subini. Ukukhetha ukuhlukahluka okulungile ngezakhiwo ezazifunayo zefilimu kubalulekile ukufeza ukusebenza okufunayo.

2.5 Ukuvumelana Ukuvumelana:
I-Hemc kufanele ihambisane nezinye izithako noma izengezo ezikhona ekwakhekeni. Ukungasebenzi kungaholela ezinkingeni ezinjengokwehlukaniswa kwesigaba, ukulahleka kwe-viscosity, noma ukonakaliswa kokusebenza. Ukuhlolwa kokuhambisana kufanele kwenziwe lapho kwenziwa imikhiqizo emisha noma ukulungisa ukwakheka okukhona.

2.6 Izici zezemvelo:
Izici zezemvelo ezifana nokushisa, umswakama kanye nokuvezwa kwe-UV kufanele futhi kubhekwe. Izinhlobo ezithile ze-hemc zingase zizinze ngaphansi kwezimo ezithile, zibenze balungele izinhlelo zokusebenza zangaphandle noma ukwakheka okuvezwe yizimo zemvelo ezinokhahlo.

3. Inqubo yokukhetha:

3.1 Izidingo Zencazelo:
Qala ngokuchaza ngokucacile izidingo zakho kanye nokucaciswa kwezinhlobonhlobo ze-hemc. Cabanga ngezinto ezifana nokubonaka, ukugcinwa kwamanzi, izakhiwo ezakha amafilimu, kanye nokuhambisana nezinye izithako.

3.2 Yenza isivivinyo:
Uma usuthole izinhlobo ezingaba khona ze-hemc ezihlangabezana nezidingo zakho, yenza ukuhlola ngokuphelele ukuze uhlole ukusebenza kwawo kuhlelo lwakho lokusebenza oluthile. Lokhu kungafaka phakathi ukuzilolonga kwelebhu, izivivinyo zokushayela izindiza noma ukuhlolwa kwensimu, kuya ngohlobo lwephrojekthi.

3.3 Bheka izindleko:
Qhathanisa izindleko zezinhlobonhlobo ze-hemc ngenkathi ucubungula ukusebenza kwazo kanye nokufaneleka kwazo kuhlelo lwakho lokusebenza. Ukufinyelela imiphumela efiselekayo ngaphakathi kwezinkinga zesabelomali, ibhalansi kufanele ihlaselwe phakathi kokusebenza kwezindleko kanye nekhwalithi yomkhiqizo.

3.4 Ukubonisana Nabathengisi:
Thintana nomhlinzeki we-hemc noma umenzi wokuqoqa imininingwane eminingi ngemikhiqizo yabo kanye nezinsizakalo zokusekelwa kwezobuchwepheshe. Banganikeza ukuqonda okubalulekile nezeluleko ezisuselwa kubuchwepheshe babo kanye nesipiliyoni sabo.

3.5 Ukubuyekezwa kwedatha yezokuphepha:
Qiniseka ukuthi izinhlobonhlobo ze-hemc ukhetha ukuhlangabezana nezidingo zokuphepha nezilawuli ezihambelana nemboni yakho. Buyekeza amashidi wedatha yokuphepha kanye nezitifiketi zokulawula ukuze uqinisekise ukuhambisana namazinga nemigomo efanelekile.

3.6 Hlaziya izinzuzo zesikhathi eside:
Cabanga ngezinzuzo zesikhathi eside zokukhetha izinhlobonhlobo ze-hemc ezilungile, njengokusebenza okuthuthukile komkhiqizo, ukuqina okuthuthukile kanye nezindleko zokulungiswa okuncishisiwe. Ukutshala imali ngekhwalithi ephezulu ye-hemc phezulu kungaholela emalini ebalulekile nezinzuzo zokuphila komkhiqizo.

4. Ekuphetheni:
Ukukhetha izinhlobo ezifanele ze-Hemc zidinga ukucatshangelwa ngokucophelela kwezici ezinjengokubona, ukugcinwa kwamanzi, izakhiwo ezakha amafilimu, ukuhambisana kanye nezindleko. Ngokuqonda izidingo zakho ezithile nokwenza ukuhlolwa okuphelele nokuhlola, ungakhetha izinhlobonhlobo ze-hemc ezihlangabezana nezidingo zakho futhi zinikeze ukusebenza okuhle kakhulu kuhlelo lwakho lokusebenza. Ukusebenza nabaphakeli nabakhiqizi kunganikeza ukusekelwa okubalulekile nobuchwepheshe kuyo yonke inqubo yokukhetha, ukuqinisekisa ukuphumelela kwephrojekthi noma umkhiqizo wakho.
