Iyini injongo ye-gypsem eyengeziwe emshinini uma i-clinker igotshwa?

Isikhathi:12 Septhemba 2025

Igesi ibalulekile emisebenzini yokukhiqiza isamente, ikakhulukazi ngesikhathi sokugaya i-clinker. Le ndatshana ihlola inhloso yokwengeza igesi emshinini lapho i-clinker igaywa, ichaza imisebenzi yayo nezinzuzo ekukhiqizeni isamente.

Ukuqonda i-Clinker ne-Cement

Ngaphambi kokungena emsebenzini we-gypsum, kubalulekile ukuqonda izingxenye eziyisisekelo ezithintekayo ekukhiqizeni i-cement:

• Clinker: I-Clinker yinto enomumo eyenziwa esigabeni sokushisa ngesikhathi sokukhiqiza isement. Iqukethe kakhulu i-calcium silicates futhi iyingxenye eyinhloko ye-sement.
• Ishukela: Ishukela yinsiza yokubopha esetshenziselwa ukwakha eyakhiwe ngokuphosa i-clinker nezinto ezengeziwe.

Indima yeGypsum kuSement

I-gypsum ifakwa ku-clinker ngesikhathi sokugaya kokugcina ukuze kulawulwe izinto eziningi zomkhiqizo ophelile. Nansi eminye yemibandela ebalulekile yokufakwa kwayo:

1. Ukumisa Umthetho Wesikhathi

Enye yezinhloso eziyisisekelo zokwengeza i-gypsum ukuvula isikhathi sokubamba kwe-cement. Ngaphandle kwe-gypsum, i-cement izobamba cishe ngokuzenzakalelayo ngemva kokuhlanganiswa namanzi, okwenza kube sengozini ngendlela yokwakha.

• Isikhathi sokuqala sokubeka: Igypsum ihlisa isikhathi sokuqala sokubeka, ivumela isikhathi esanele sokusebenza ukuze uxube, uthathe, futhi ubeke i-cement.
• Isikhathi Sokugcina Sokubekwa: Lokhu kuqinisekisa ukuthi isitini siba nsomi ngesivinini esilawulwayo, okubalulekile ukuze kuqinisekiswe ubuqotho besakhiwo.

2. Ukuvinjwa Kwe-Flash Setting

Ukubekwa kwe-flash kubhekisela ekugxumeni okusheshayo kwe-cement ngaphandle kokwengeza i-gypsum. Le phenomene ingaholela ekutheni:

• Ukuhlangabezana okuphansi kobungcweti
• Amandla ancishisiwe
• Ukusebenza okungalindelekile

I-gypsum isebenza njengokwehlisa isivinini, ivimbela ukufakwa okusheshayo futhi iqinisekisa umkhiqizo ofanele nokuqiniseka.

3. Ukuthuthukiswa kweKhwalithi yeSimenti

IGypsum iyasiza ekuthuthukiseni ikhwalithi yesamente ngokuthi:

• Ukuqinisa ukuthuthukiswa kwamandla
• Ukuphucula ukusebenza nokuphothulwa
• Ukuqinisekisa indawo efanayo nenhlelekile.

Ukuphendula Kwemichamo Ephathelene

Ukwengeza i-gypsum ku-clinker kuhilela ukuphendulwa kwemikhiqizo okubalulekile ukuze kube nezici ezifunekayo ze-cement:

1. I-Tricalcium Aluminate (C3A) Ukuphendula: Uma amanzi engezelelwa kumphako, i-C3A iphendula ngokushesha namanzi, okuholela ekubeni kusebenze ngokushesha.
2. Indima yeGypsum: I-Gypsum iphendula ne-C3A ukukhiqiza i-calcium sulfoaluminate, evimba inqubo yokuhlanganiswa futhi ilawula isikhathi sokumisa.

Okuhle kakhulu okuqukethwe kweGypsum

Inani le-gypsum elengezwayo ku-clinker libalulekile futhi ngokuvamile lihlala phakathi kuka-3-5% ngokwesisindo. Okuqukethwe okuhle kakhulu kuncike ku:

• Izimpahla ezithile ze-clinker
• Isikhathi sokumisa esifisayo namandla e-cement.
• Izimo zemvelo nezimfuneko zokwakha

Isiphetho

Ngokuhlanganisa, ukufaka igypsum ngesikhathi sokugqoka i-clinker kuyisinyathelo esibalulekile ekukhiqizeni i-cement. Kusekela isikhathi sokusetha, kuvinjela ukusetha okusheshayo, futhi kuthuthukisa ikhwalithi jikelele ye-cement. Ukuqonda indima ye-gypsum kusiza ekukhiqizeni impahla yokwakha ethembekile nephumelelayo ehambelana nezidingo zokwakha ezihlukahlukene nezokwakha.
