Cara Membuat Pembersih Karat

Biasanya setelah hujan-hujanan beberapa bagian motor pasti berkerak dan berkarat.

Di bawah ini cara membuat sendiri cairan untuk memberishkan karat, bukan cuma untuk motor, tapi bisa juga untuk membersihkan karat di pagar, dan perabot rumah tangga.

Bahan untuk membuat pembersih karat:

1. Hydrogen Fluoride (HF) 80 %, 200 ml

2. Air 100 - 200 ml

Agar tidak karatan lagi harus dioles oli sedikit setelah diaplikasikan.

Untuk karat besi yang sudah lama, perbandingannya 1:1.

HF merupakan asam kuat, memiliki bau yang menyengat.

Gunakan sarung tangan serta masker, karena bisa membuat gatal dan iritasi jika terkena kulit. Jika terkena, guyur dengan air mengalir, serta gunakan sabun.


Beda HF, HCl dan Nitrit?

Kadar HF lebih kuat dibanding HCl, sedangkan Nitrit asam biasa.

Untuk kerak tebal bisa gunakan HF, jika kerak tipis bisa gunakan HCl.

Ukuran kadar HF seperti Alkohol, ada 50% s/d 100%


HF Untuk Membersihkan Jamur Kaca

HF+Aquadest (air murni/H2O) bisa digunakan sebagai pembersih jamur kaca. Perbandingan HF : Air = 1 ml : 10 ml &  tambahkan sabun colek 1. Setelah dioleskan, segera siram dengan air.

Untuk jari-jari motor pemakaian HF takarannya > HF : Air = 40 ml : 60 ml

Untuk membersihkan kerak  panci  takarannya HF : Air = 150 ml : air 250 ml

The Rise of Decentralized Social Networks

Some of them have been around for more than a decade, such as the Diaspora, which began in 2010. In comparison, Facebook debuted in 2006, just four years before Diaspora. The idea is to go back to the good old days of the Internet in the early 90's, commonly known as Web 1.0 (as you know, we are living in Web 2.0 at this time). Users can publish content directly to user-friendly decentralized sites, bypassing corporate intermediaries and intended approaches. Anyone can create and run their own version of the ideal on one platform. This is what decentralized social networks do with the concept of "free will." There is no central authority (person, server, or company) that dictates the rules. The best thing is that they give creators the opportunity to monetize their work and earn tokens tha

Do We Need to Regulate 'The Freedom'?

The spread of misinformation and irresponsible content on social media platforms has led many to believe that these platforms need to be more tightly regulated. Negativity is a goal for social network firms since it is suitable for income flow. Negativity sells on social media because it draws users' attention more than positive content and keeps them scrolling on their devices. The algorithms boost negative content while stifling positive content. That means users are not satisfied with how big businesses are handling the risks of misinformation and censorship, privacy, political neutrality, user control, and malicious activity on social networks. The purpose of this business strategy is to dissuade people from posting harmful information on social media networks. These concerns have led to the consolidation of social networks. Deleting objectionable user-generated content is usu

What is a Decentralized Social Network and How Valuable is it?

Similar to cryptocurrencies, social networks that are based on blockchain technology and run-on independent servers rather than central servers owned and operated by businesses or organizations can be described as decentralized. No phone number or email address is required to use the blockchain. Their technology enables peer-to-peer interactions instead of mediated private platforms. Users can meet, flirt, chat and share in their community forums. This structure enables democratic processes between users or communities and is managed independently of intermediaries. They are powered by distributed ledger technologies, where activities on the platform are recorded on the decentralized protocol and user data is stored on a blockchain and cannot be removed by any central authority like in the case of Facebook. Decentralized platforms use technology that eliminates unnecessary points in the platform's technical infrastructure. Exchanges and other resources on various networks (module
