Bhí jab amháin fágtha ag criú múchta ag gléasra ceimiceach roimh atosú: cuir gasket sceite a athsholáthar ar chomhla dhá mhéadar déag taobh istigh de líne PPH lán-táthaithe. Mar gheall ar ghearradh an phíobáin bhí spól nua, táthú nua, fanacht fuaraithe agus an dara tástáil brú, ceithre huaire sa bhreis ar an scei...

Is é an rud a chinneann i ndáiríre an ritheann comhla liathróid plaisteach go ciúin ar feadh cúig bliana nó má theipeann ar an gcéad dul síos, an t-ábhar coirp, an leaistiméire rói...

Sroicheann gach rud de réir an sceidil agus ní luíonn aon rud: tomhaiseann an píopa 60.3 mm trasna an taobh amuigh, agus déantar an t-adapter a mheaisíniú ar thrastomhas lasmuigh de 50 mm. Níl ceachtar den dá lipéad ...

Féach TuilleadhWhat are the main materials of PPN pipes?
1. Modified Polypropylene (PP): PPN pipes use polypropylene (PP) as the matrix, which is β-modified or copolymerized to give it higher temperature resistance, chemical corrosion resistance, and aging resistance.
2. High Transparency and Low Water Absorption: PPN material has an extremely low water absorption rate (≈0.01%), and hardly expands in aquatic environments, making it suitable for industries highly sensitive to moisture, such as cleanrooms, pharmaceuticals, and semiconductors.
3. Excellent Mechanical Strength: The modified PPN pipe wall is dense, significantly improving impact strength and pressure resistance, and can operate stably in a wide temperature range of -10℃ to +100℃.
What are the differences between PPN pipes and ordinary PP pipes (PPH)?
1. Compositional Differences: PPN pipes use polypropylene raw materials directly, while PPH pipes are β-modified from ordinary PP to form a more uniform and delicate β-crystalline structure.
2. Performance Comparison:
Chemical Resistance: PPN performs better in strong acid and alkali environments, exhibiting stronger corrosion resistance; while PPH also possesses good chemical resistance, it is slightly inferior.
High Temperature Resistance: PPN can be used continuously at temperatures above 100℃, suitable for high-temperature process pipelines; the maximum operating temperature of PPH is generally around 90℃.
Abrasion and Aging Resistance: PPN pipes exhibit superior abrasion resistance and anti-aging properties, resulting in a longer service life, making them particularly suitable for harsh conditions such as chemical and pharmaceutical industries.
3. Application Scenarios: PPN is more inclined towards high-end photovoltaic, semiconductor, chemical, and pharmaceutical fields where extremely high material purity and temperature resistance are required; PPH is commonly used in general industrial pipelines, water supply and drainage, and medium- and low-pressure transmission systems.
